Brimstone
Fae captivity deepens as stakes rise and hearts shift
By Ember · Updated July 2, 2026
Brimstone picks up where Quicksilver left you breathless and refuses to let you rest. The frozen fae realm expands to include vampire courts and deeper political intrigue, raising the stakes for Saeris and Kingfisher beyond personal survival. Callie Hart shifts to dual POV, letting readers inside both heads for the first time, and the effect is devastating. You see how they each process what's growing between them while war and court machinations push them toward impossible choices.
The captivity dynamic from the first book hasn't vanished. It's evolved. The relationship grows not because one person suddenly has power but because both choose connection despite every structural reason not to. That choice feels earned rather than convenient. The slow burn that started in Quicksilver builds to genuine heat here, and the intimacy lands because vulnerability still carries risk in this world.
Hart doesn't lighten the darkness. The fae remain morally complex, the violence has consequences, and the romance exists alongside trauma rather than erasing it. What changes is the depth of understanding between two people who started as enemies and are becoming something neither expected. The sequel delivers on the promise of the first book while expanding the world and raising what's at stake.

What readers want after finishing Brimstone
You're looking for romantasy that doesn't reset emotional progress between books. Where the sequel deepens what the first book established rather than manufacturing new external conflict to keep the couple apart. Where intimacy grows through shared danger rather than contrived misunderstandings.
You want fae worlds that feel genuinely alien, with their own logic and brutality. Courts where politics matter as much as romance, where survival requires reading power dynamics correctly, and where being human in a fae realm means constant vulnerability. Settings that stay dangerous even after the romance begins.
What keeps you reading is the combination of character depth and high stakes. Heroes whose damage is specific rather than generic, whose choices hurt even when they're trying to protect, whose morally gray decisions reflect the world they're navigating. Romance that asks whether love can exist when it started in captivity and whether healing happens alongside desire or after.

Book recommendations
Quicksilver
by Callie Hart
The first book in Fae & Alchemy. Start here to understand how Saeris and Kingfisher's relationship began with genuine enmity and forced proximity in a frozen fae realm where humans are property.
Hunting Adeline
by H.D. Carlton
The sequel to Haunting Adeline. Escalating stakes, deeper psychological intensity, and a captivity dynamic that evolves without erasing its darkness. Even more intense than the first.
A Court of Mist and Fury
by Sarah J. Maas
The second ACOTAR book handles the sequel challenge well. Feyre escapes one captor and finds complexity with another. Fae politics expand, power dynamics shift, and the romance deepens through shared purpose.
The Kingdom of the Wicked
by Kerri Maniscalco
A witch investigating murders makes a deal with a demon prince. Dark fantasy with Italian setting, enemies to lovers with real enmity, and sequels that escalate rather than reset tension.
Gild
by Raven Kennedy
A woman with golden skin kept as property moves from one captor to another. Hart readers will recognize the honest treatment of captivity dynamics and morally gray heroes whose protection comes with costs.
Common questions
Do I need to read Quicksilver before Brimstone?
Yes, absolutely. Brimstone is a direct sequel continuing the story immediately. You'll miss essential context, character development, and why the dynamics matter if you skip the first book.
Is Brimstone darker than Quicksilver?
It's deeper rather than necessarily darker. The stakes escalate, the intimacy becomes explicit, and the fae politics grow more complex. The darkness doesn't increase so much as reveal more layers.
When does the third book in the trilogy release?
Expected November 2026. Hart tends to hit her announced dates, but check her social media for updates closer to release.
Is the dual POV better than single POV in Quicksilver?
Most readers think so. Getting inside Kingfisher's head adds depth to his choices and makes the slow burn more intense. But if you prefer mystery around the hero's thoughts, single POV has its advantages.
