Callie Hart hits New York Times No. 1

British author Callie Hart has another bestseller at the top of the romantasy market. Parade reported on August 6 that Hart’s “Brimstone,” the second book in her Fae & Alchemy series, became an instant No. 1 New York Times bestseller, extending the run of a franchise that had already broken out with “Quicksilver.” Hachette Book Group lists “Brimstone” as a 672-page novel published on November 18, 2025, by Grand Central Publishing, and describes Hart as a “#1 New York Times bestselling author.” Goodreads shows the sequel with more than 344,000 ratings, while the series page identifies it as book two in a planned trilogy. (parade.com) Parade tied the latest ranking to the broader strength of romantasy in 2026, a year in which the genre has remained prominent across bestseller coverage and reader-tracking lists. Goodreads’ “Most Read Books This Year” page, generated July 19, 2026, is one of the platforms Parade cited in measuring that momentum.

The outlet described it as the sequel in Hart’s Fae & Alchemy series and said it reached the top spot as an “instant” bestseller. Goodreads’ series page lists “Brimstone” as book two, following “Quicksilver.” Hachette’s book page says the novel was released in hardcover and ebook formats on November 18, 2025. (parade.com) ### How did Hart get here? “Quicksilver” was the breakout title that established the series. Hachette says that book went on sale in U.S. hardcover on September 10, 2024, and now markets it as a New York Times bestseller with more than three million copies sold across the Fae & Alchemy series. (parade.com) Callie Hart’s own press page says UK and Commonwealth rights for “Quicksilver” were acquired by Hodderscape after a 10-way auction, while North American rights went to Forever, an imprint of Grand Central Publishing. (goodreads.com) That sequence helps explain how a self-published breakout was moved into major commercial distribution. ### What do the reader numbers show? Goodreads gives the clearest public measure of scale. (hachettebookgroup.com) The Fae & Alchemy series page shows “Quicksilver” with roughly 953,000 ratings and “Brimstone” with roughly 344,000 ratings, figures that place both books among the site’s most heavily logged fantasy-romance titles. Parade has separately reported that Hart’s books rank among Goodreads’ most-read titles of 2026. (calliehart.com) Goodreads’ own “Most Read Books This Year” page defines that list as books readers marked as finished during the year, giving a concrete basis for the “most read” label. ### Why is the sequel getting attention now? August 6 is when Parade published its latest piece linking Hart’s chart performance to the continuing strength of romantasy. (goodreads.com) The article framed “Brimstone” as part of a market still being driven by reader communities, sequel demand and crossover visibility beyond niche fantasy audiences. (parade.com) Hachette is also using the commercial success of the series in its marketing. The publisher’s pages for both “Quicksilver” and “Brimstone” say a Netflix feature-film adaptation is in development and repeat the “over three million copies sold” figure for the Fae & Alchemy series. ### What comes next for the series? (parade.com) Goodreads’ November 2026 popular-books page points to a third Fae & Alchemy installment due later this year. The entry says the trilogy will conclude in November 2026, following “Quicksilver” and “Brimstone.” Hachette’s existing series pages and Goodreads’ annual reading trackers are the main public places to watch for the next milestones — including release timing, preorder activity and whether Hart’s books remain on 2026’s most-read lists.
