Brimstone — Fae & Alchemy, Book Two

More of Everything Fans Wanted

Brimstone is the eagerly awaited second book in Callie Hart’s Fae & Alchemy series, the follow-up to the 2024 breakout Quicksilver, and it delivers exactly what its enormous readership came for: more world, more heat, more danger, and a deeper love story. As a darkness falls across the fae kingdom of Yvelia, Saeris Fane and the fearsome warrior Kingfisher are drawn together into a fight to save the realm and the people they care about, and the stakes — political, supernatural, and romantic — climb steeply. For readers who devoured the enemies-to-lovers tension of the first book, Brimstone is a bigger, richer continuation that rewards their investment.

At nearly seven hundred pages, it is a substantial commitment, but for fans of the immersive, settle-in style that defines Hart’s romantasy, the length is part of the appeal.

The Dual Perspective

The most significant change in Brimstone is structural: where Quicksilver was told entirely from Saeris’s sharp, sarcastic point of view, the sequel adds Kingfisher’s perspective, alternating between the two leads. This dual point of view is a gift to readers who fell for the romance, finally opening up the interior life of the brooding, infuriating fae warrior who was previously seen only from the outside. Getting inside Kingfisher’s head deepens the emotional texture of the relationship and adds new dimensions to a dynamic that the first book could only show from one side. It is a smart evolution that enriches the love story considerably.

The Romance Deepens

With the enemies-to-lovers antagonism of the first book largely behind them, Brimstone moves the central relationship into deeper, more committed territory, while keeping the tension and heat that Hart’s romance background brings to the genre. The connection between Saeris and Kingfisher is tested by the rising dangers and by the secrets and burdens each carries, and the dual perspective lets readers feel the relationship from both sides. For those who came to the series for its spicier, more passionate take on fae romance, Brimstone delivers the deepening payoff they hoped for.

A Kingdom in Peril

The stakes expand significantly in Brimstone. The darkness threatening Yvelia, the gathering forces of war, and the dangers facing the characters’ friends and allies all escalate, broadening the scope from the more personal journey of Quicksilver into something with kingdom-wide consequences. Hart’s immersive worldbuilding, anchored by the distinctive alchemy-based magic and the frozen fae setting, expands here, giving readers more of the richly imagined world to explore. The larger conflict gives the romance a backdrop of genuine peril and raises the urgency of everything the characters fight for.

Saeris’s Voice Endures

Even with the addition of Kingfisher’s perspective, Saeris’s sharp, sarcastic voice remains a highlight. The wit, pragmatism, and hard-won toughness that made her such a memorable heroine in Quicksilver carry through, and her chapters retain the distinctive energy that distinguished the first book. Hart’s gift for a strong, characterful protagonist is one of the series’ chief pleasures, and Brimstone keeps Saeris front and centre even as it widens the lens.

A Middle-Book Commitment

Brimstone is the second book of a planned trilogy, and it carries the particular weight of a middle installment — escalating the conflict and deepening the relationships while leaving the largest resolutions for the finale. It depends entirely on Quicksilver and ends with the series’ larger questions still open, pulling readers toward the concluding volume. The length and the middle-book pacing mean it is a book for committed fans rather than newcomers, but for those readers, it is a deeply immersive continuation.

The Verdict

Brimstone is a bigger, hotter, dual-POV sequel that gives Quicksilver fans more of everything they loved — a deeper romance, a wider and more perilous world, and the welcome addition of Kingfisher’s perspective. Long, immersive, and rich with the heat and banter that define Hart’s work, it advances the Fae & Alchemy series with confidence and leaves readers eager for the finale. For fans of the deep, spicy end of romantasy, it is a rewarding return to one of the genre’s most talked-about recent worlds.

The Power of a Second Perspective

The single most consequential choice in Brimstone is the shift to dual point of view, and it deserves emphasis because of how much it changes the reading experience. In Quicksilver, Kingfisher was a closed book — magnetic, infuriating, and entirely opaque, seen only through Saeris’s wary, sarcastic eyes. Opening his perspective in Brimstone transforms the romance from a one-sided pursuit into a genuine two-hander, letting readers feel the relationship from both sides and understand the burdens and history that the first book could only hint at. This is a technique romantasy uses often, and for good reason: a beloved, mysterious love interest becomes even more compelling once readers are allowed inside his head, and the emotional stakes of the relationship deepen accordingly. Hart uses the dual POV to enrich the central pairing without sacrificing Saeris’s distinctive voice, which remains as sharp as ever. For fans who fell for the enemies-to-lovers dynamic of the first book, getting Kingfisher’s interiority is exactly the gift they hoped the sequel would deliver, and it is a large part of why Brimstone satisfies.

Our rating: 4.3/5 — A bigger, hotter, dual-POV sequel that deepens the romance and raises the stakes across the fae kingdom, giving Quicksilver fans more of everything they wanted.
