Brimstone is a 2025 romantasy novel by British author Callie Hart, the second in her Fae & Alchemy trilogy and the sequel to Quicksilver (2024). Forever, an imprint of Grand Central Publishing, published the book on November 18, 2025, with Hodderscape releasing the UK edition. The novel appeared on The New York Times Best Seller list in 2025.
Unlike Quicksilver, which was narrated solely from the protagonist's perspective, Brimstone employs dual point of view, alternating between Saeris Fane and Kingfisher. Hart told E! News she wanted readers to "meet a whole new version" of Kingfisher through his chapters, describing him as more emotionally open and vulnerable than in the first book.
