Quicksilver Hooked Me. Brimstone Nearly Made Me Quit the Series.

This review focuses primarily on my reading experience, the pacing, and the difference between the first two books. I will warn you before discussing later relationship developments, magical revelations, or the way Brimstone prepares the story for Book Three.

I did not pick up Brimstone casually because I happened to notice it sitting on my shelf. I planned for this book. I arranged my reading so I would finish Rose in Chains the day before release, leaving my schedule completely open to begin the sequel the moment it became available. That is how excited I was to return to Saeris, Kingfisher, and the world Callie Hart had created in Quicksilver.

Then the book I had planned around took me approximately four months to finish.

For context, I normally finish a book in roughly two weeks, often much faster when I am deeply invested. Four months is not a slightly slower reading experience for me. It means I repeatedly set the book down, struggled to convince myself to return, and read other things because almost anything sounded more appealing than continuing the sequel I had once been desperate to begin.

Quicksilver earned five stars without hesitation. Brimstone received three, and most of those stars came from the attachment the first book had already created. I am still invested enough to read Book Three, but the blind excitement is gone. At this point, the next installment has to prove that the series can recover the focus, tension, romance, and momentum that made Quicksilver so difficult to put down.

BookTok Got Me Again—and This Time It Was Right

TikTok and BookTok have convinced me to read plenty of books, with wildly inconsistent results. Sometimes the hype leads me to a new obsession. Sometimes I finish the book wondering whether everyone online read a completely different version than I did.

Quicksilver was one of the times BookTok got it right. The videos, quotes, and general obsession surrounding the story made me curious, but the book did not depend on that hype to carry it. Once I entered the story, it gave me its own reasons to stay.

The twists kept changing what I thought I understood without making the entire plot feel deliberately confusing. The fantasy elements supported the story rather than burying it beneath explanations. Saeris and Kingfisher had the kind of dangerous pull that made every conversation feel as though something might finally break between them, even when neither was prepared to admit exactly what was happening.

Most importantly, the book had momentum. There was always a reason to continue: another question, another revelation, another shift in the relationship, or another piece of the world becoming visible. I did not have to remind myself that the story would probably become interesting again soon. It already was.

Everything Quicksilver Did Right

Quicksilver worked because its individual elements fed into one another. The romance was connected to the danger. The danger was connected to the magic. The magic revealed more about the world and the characters, which then created new tension inside the romance. Nothing felt as though it had been added merely because a romantasy checklist required it.

Saeris held my attention because she entered an unfamiliar and dangerous situation without becoming passive inside it. Kingfisher was compelling because the story gave him power, mystery, and emotional weight without revealing everything about him immediately. Their connection developed through suspicion, attraction, frustration, and the constant possibility that one of them knew something the other desperately needed to understand.

The romantic tension mattered because it was not separate from the larger story. Every new piece of information affected the way Saeris and Fisher viewed one another. Their attraction did not exist inside a private bubble while the fantasy plot happened somewhere else. It was tangled into the bargains, risks, loyalties, and lies surrounding them.

That balance is what I wanted from the series. I was not asking for a romance with a few decorative Fae standing in the background, and I was not asking for a dense fantasy story that remembered every hundred pages that the main characters were attracted to each other. Quicksilver gave me both sides at once, which is why I devoured it and trusted the sequel before I had read a single page.

I Planned My Reading Around Brimstone

The timing around Brimstone matters because it shows how completely the first book had earned my excitement. I was already reading Rose in Chains, so I calculated my schedule and finished it the day before Brimstone released. I did not want another book standing between me and the sequel.

There is a particular kind of excitement that comes with opening a release you have been actively waiting for. You already know the characters. You remember where the previous story left you. You have questions waiting for answers and expectations built from everything the first book did well.

I expected a shift because sequels often need to expand the world. The characters are no longer discovering everything for the first time, the political conflict becomes larger, and the story has to begin moving toward whatever the series is ultimately building. I was completely prepared for more lore, more responsibility, and a plot that reached beyond the immediate relationship.

What I was not prepared for was how quickly the energy disappeared.

Then It Took Me Four Months to Finish

The beginning of my struggle was not dramatic. I did not reach one terrible scene, slam the book shut, and decide I hated it. The problem was quieter and more frustrating: I simply stopped wanting to pick it back up.

I would read for a while, set it aside, and feel no urgency to return. Days became weeks. I read other books in between because I still wanted to read; I just did not want to continue Brimstone. Every time I returned, I had to rebuild the momentum the story itself was no longer creating for me.

That distinction matters because this was not a reading slump. The problem was not that I had temporarily lost interest in books. Other stories could hold my attention perfectly well. Brimstone was the one becoming difficult.

Eventually, finishing became less about enjoyment and more about refusing to quit after investing so much time. I had loved Quicksilver, I still cared about the larger story, and I wanted to know whether the ending would justify what felt so scattered in the middle. After several months, abandoning it seemed almost more irritating than forcing myself to continue.

That is not the kind of determination a sequel should inspire.

World-Building Was Not the Problem

I have seen disappointing sequels defended with the idea that the story is simply “more fantasy” than the first book, as though readers who miss the earlier momentum must only be interested in romance. That was not my problem with Brimstone.

I enjoy fantasy. I expect a series to expand its lore, politics, conflicts, magical systems, and history. A second book should reveal that the world is larger than the portion we experienced in the first installment. It should deepen what we know and create complications that could not have existed before the characters crossed certain boundaries.

My issue was the delivery. The world-building did not feel as though it was pulling the story into a larger, more purposeful shape. It felt as though too many pieces had been gathered, introduced, and pushed forward without enough connection between them. Instead of becoming more immersed, I frequently felt as though I was being redirected toward another thread before the previous one had developed enough weight.

The book contained plenty of material. That was never the problem. The problem was that the material did not combine into a satisfying reading experience. More lore does not automatically create more depth, especially when the reader spends much of the book wondering which part is supposed to matter most.

It Felt Like Everything Cut from Quicksilver Had Been Shoved Together

The blunt version of my opinion is that Brimstone often felt less like a purposeful second installment and more like leftover material from Quicksilver had been gathered, expanded, and shoved into one long filler book.

That does not mean nothing important happened. The story clearly contained information and setup intended to matter later. The characters encountered new problems, the world expanded, and pieces were moved into position for Book Three. I could see the work being done.

I simply did not enjoy watching it happen.

A middle book can prepare the final installment without feeling like a storage room for explanations, side threads, and conflicts that were not strong enough to carry themselves. The best sequels deepen the first story while creating their own emotional movement. They should feel necessary as books, not only as bridges between the beginning and the ending.

Brimstone rarely gave me that sense of purpose. Too many sections felt disconnected from the tension that had made the first book addictive. The pacing slowed, the focus scattered, and the story repeatedly introduced content without recreating the feeling that every chapter was taking me somewhere I needed to go.

Saeris Lost Me—and Even Kingfisher Could Not Save It

Saeris did not hold my attention in Brimstone the way she had in the first book. I do not think that means she objectively became a worse character, and I understand that her circumstances and responsibilities had changed. My connection to her simply weakened as the story around her became less focused.

Her choices felt less engaging, and she no longer carried the same energy that had made following her through Quicksilver so easy. Part of that may have come from the expanded plot pulling attention in too many directions, but the result was the same: I was spending time with a character I had previously enjoyed and feeling increasingly detached from what she was doing.

Kingfisher remained one of the reasons I cared about the series, but even he could not make me eager to return every day. That may be the clearest sign of what went wrong. The character who had helped make Book One addictive was still present, yet the story was not using his appeal effectively enough to carry the sequel.

I still love Fisher. I still wanted more from him, which is part of why the experience became so frustrating. He deserved a stronger story around him, one that allowed his relationships, conflicts, and presence to create the same impact they had before. Instead, he often felt trapped inside the same scattered structure that was weakening everything else.

The Romantic Momentum Disappeared

The relationship between Saeris and Kingfisher had been one of the strongest parts of Quicksilver. Their connection carried danger, attraction, suspicion, and emotional uncertainty. Every interaction appeared capable of changing the balance between them, which made even quieter scenes feel important.

I missed that push and pull in Brimstone. The romance did not need to repeat the exact tension of the first book because their relationship had already changed, but it still needed meaningful emotional progression. I wanted the chemistry to evolve rather than simply lose its charge beneath the expanding fantasy plot.

World-building and romance were never competing requirements for me. The book needed both. The political and magical conflict should have increased the pressure on the relationship, creating new risks, sacrifices, and reasons the characters might either pull together or break apart.

Instead, the romantic suspense often felt diluted. The interactions no longer carried the same anticipation, and I stopped feeling that every moment between them mattered. When a relationship is one of the reasons a first book earns five stars, allowing that momentum to disappear in the sequel leaves a very noticeable hole.

Light Brimstone Spoilers Begin Here

The following sections discuss the broader direction of the relationship, magical developments, and how Brimstone prepares the story for Book Three. Specific plot events remain limited because my main concerns are structural rather than twist-based.

Three Stars Because I Was Already Too Invested to Quit

My three-star rating does not mean I enthusiastically enjoyed most of Brimstone. It reflects the fact that enough of the original investment survived to carry me through a book I otherwise might have abandoned.

I wanted to understand where the larger conflict was going. I wanted answers about the magic and relationships. I kept hoping that the scattered pieces would eventually form a shape strong enough to make the struggle worthwhile. Some developments did matter, particularly in preparing the next stage of the story, but the payoff never completely repaired the experience of reaching them.

There is also a stubbornness that appears once I have spent months on one book. Quitting early can feel freeing. Quitting after dragging myself through most of a long sequel feels as though the book has defeated me personally, which is not necessarily a healthy approach but is apparently mine.

The rating therefore belongs partly to Brimstone and partly to the strength of Quicksilver. The first book had made me care enough that the sequel still had something to spend. By the final pages, however, most of that credit had been used.

Book Three Has a Hell of a Lot to Repair

I will read Book Three because I still want to know how the story ends. I care about Kingfisher, I remain interested in the world beneath the clutter, and I need to see whether the material established in Brimstone becomes more meaningful once the series reaches its payoff.

My expectations are now significantly lower than they were before Book Two. I am no longer planning my reading schedule around release with complete confidence that I am about to disappear into another five-star experience. The next book needs to earn that trust again.

I need focus. The story can be large without feeling scattered, and the fantasy can be detailed without making every chapter feel disconnected from the one before it. I need twists that change the direction of the story rather than adding another thread to an already overcrowded plot.

I also need the relationship between Saeris and Fisher to regain its emotional force. I do not expect them to return to the exact dynamic from Quicksilver, but I need chemistry, tension, and meaningful progression. Their bond should influence the story rather than becoming one more element buried beneath the setup.

Most importantly, Book Three has to make Brimstone feel necessary. If the final installment can connect the scattered pieces and turn them into genuine payoff, I may look back on parts of the sequel with more appreciation. If it cannot, then Book Two will remain an overly long interruption between the story that hooked me and the conclusion I was trying to reach.

I Will Read It—but Apparently I Need a Bribe

My plan for Book Three says more about the damage Brimstone did to my trust than any rating could.

Before I begin it, I am going to start another duet or series that I already desperately want to continue. Then I will pause that story, read Book Three, and use the waiting book as motivation to finish.

I now need to bribe myself with another fictional world to make sure I complete the next installment in a series that began with a five-star obsession.

That is ridiculous, but it is also honest. I do not want another four-month struggle where every other book on my shelves becomes more appealing. Having something exciting waiting afterward gives me a finish line if the final installment begins losing me again.

Of course, I would love for that entire plan to become unnecessary. I want to open Book Three, recognize the energy I loved in Quicksilver, and become irritated that I ever doubted the series could recover. I want Fisher to matter again, Saeris to hold my attention, and the story to move with enough purpose that my backup book sits forgotten for several days.

I am simply no longer trusting that outcome without insurance.

Is the Fae & Alchemy Series Still Worth Reading?

I would still recommend Quicksilver. The first book earned its five stars and remains worth experiencing for the romance, twists, world, characters, and momentum that made it so difficult to stop reading.

The warning belongs to Brimstone. Readers should know that the second book may feel dramatically different from the first. It expands the fantasy and larger conflict, but the pacing is slower, the structure feels less focused, and the romantic tension may not provide the same pull.

The series may still work for readers who enjoy:

• Fae romantasy with alchemy and dangerous magic
• Powerful, morally complicated love interests
• Large fantasy conflicts that expand across multiple realms
• Romances tied directly to magical and political consequences
• Detailed lore and setup for a larger conclusion
• Series that require patience through the middle installment

I would be more cautious when recommending it to someone who needs consistent pacing, a focused plot, or strong romantic momentum throughout every installment. If Quicksilver works for you because of the tension and addictive pace, you may feel the loss of both more sharply in Brimstone.

The most accurate recommendation I can give is this: read Quicksilver because it is a five-star experience. Continue into Brimstone knowing that the focus, chemistry, and momentum may not survive the transition.

My Final Reading-Room Verdict

Quicksilver made me trust this series enough to plan my reading around the sequel. It gave me compelling characters, a relationship I wanted to follow, twists that kept the story moving, and a fantasy world that felt exciting rather than exhausting.

Brimstone took that trust and stretched it across four months.

The problem was not that the sequel contained more lore or focused on a larger conflict. I wanted expansion. What I received felt disjointed, overfilled, and unable to recreate the tension that had made the first book work so well. Saeris became less engaging for me, Kingfisher lost impact inside the scattered story, and the romance no longer carried the same dangerous energy.

Three stars feels fair because I did finish, and enough of my investment remains that I will continue. It would be dishonest, however, to pretend that finishing meant I was enjoying myself. Most of the motivation came from the five-star book that had already made me care.

Book Three now has to prove that Brimstone was building toward something worth the struggle. I need it to restore the focus, emotional tension, chemistry, and narrative momentum that disappeared along the way.

I hope it does.

I am also preparing a backup series in case it does not.
