Return to the explosive world of Fae & Alchemy with Brimstone, the #1 New York Times bestselling second installment in Callie Hart's blockbuster romantasy series. Featuring fierce heroines, dangerous fae, unforgettable slow-burn romance, razor-sharp banter, and breathtaking action, this epic fantasy continues the story that began in Quicksilver.

Brimstone is Book 2 in the Fae & Alchemy Series and is not a standalone. It should be read after Quicksilver.

Saeris Fane has spent her life surviving by keeping dangerous secrets.

But after accidentally reopening a gateway between worlds, binding herself to the powerful Fae warrior known as Kingfisher, and discovering the truth about her extraordinary alchemical abilities, there is no turning back.

As ancient enemies rise and the fragile balance between realms begins to crumble, Saeris must navigate deadly alliances, impossible choices, and powerful magic that could determine the fate of both worlds. Every bargain comes with a price, every secret has consequences, and the growing bond between Saeris and Kingfisher may prove just as dangerous as the enemies hunting them.

Packed with breathtaking world-building, epic battles, unforgettable romance, and shocking twists, Brimstone delivers another addictive installment in one of romantasy's biggest bestselling series.

Recommended for mature readers (17+) due to graphic violence, explicit romance, and adult themes.
