Callie Hart is a British author of romance and fantasy fiction, best known for her Fae & Alchemy series. Her novel Quicksilver (2024) debuted at number one on The New York Times Best Seller list and the The Sunday Times bestseller list. [1] [2] The novel became a BookTok phenomenon and was acquired by Netflix for a seven-figure film adaptation deal. [1] [3]

Early life and career

Hart is originally from England and later relocated to California, United States. [4] In interviews, she has cited her grandmother as an early influence, stating that they would write poems and limericks together, which sparked her interest in creative writing. [5]

Hart began her writing career as a self-published author. Her debut novel, Deviant, the first book in the Blood & Roses series, was published in February 2014. [6] She went on to write more than 40 books across multiple series in the dark romance and new adult fiction genres, becoming a USA Today bestselling author. [5] [7]

Quicksilver and mainstream success

In June 2024, Hart self-published Quicksilver , her first novel in the romantasy genre, which combines elements of fantasy and romance. [3] The novel follows Saeris Fane, a young woman with alchemical powers who is transported to a realm of Fae beings and becomes embroiled in a centuries-long conflict. [4]

Initially, the book did not find significant commercial success. Hart has described the novel as her "Hail Mary" after previous releases had underperformed financially. [3] She reached out to approximately 30 BookTok content creators, offering them early copies of the book. [8] The strategy proved successful, and the novel's mentions on TikTok accumulated over three million views within the first two months. [1]

The book's viral success attracted the attention of traditional publishers. Publishing rights to the Quicksilver trilogy were sold in a 10-bidder auction to Forever, an imprint of Grand Central Publishing (Hachette Book Group). [1] UK rights were acquired by Hodderscape. [1] The traditionally published edition was released on December 3, 2024, and debuted at number one on The New York Times bestseller list the same week. [2] [9] The novel also reached number one on the Sunday Times bestseller list in the United Kingdom. [10]

Quicksilver was nominated for the Goodreads Choice Awards in the Best Romantasy category in 2024. [11]

Netflix adaptation

In December 2024, Netflix acquired the film rights to Quicksilver in a competitive auction with a seven-figure deal. [1] [12] Elizabeth Cantillon of The Cantillon Company, whose credits include Alien: Romulus (2024) and Persuasion (2022), was attached to produce. [1] Hart serves as executive producer on the project. [9]

Hart stated in interviews that maintaining the adult tone of the source material is her priority for the adaptation. "This is a very graphic book in many different ways. It's dark. It's sexy. It has graphic content and violence in all kinds of different ways," she explained. "My main goal here is to make sure that the basis of the movie isn't lost." [9]

As of November 2025, a screenplay had been completed and the production was seeking a director. [13]

Literary influences

Hart has cited J. R. R. Tolkien's The Lord of the Rings and Frank Herbert's Dune as major influences on her work. [14] She has described drawing inspiration from Herbert's work for the desert landscape of Zilvaren in Quicksilver, and from Tolkien for the novel's world-building and naming conventions. [14] [8] Other authors she has mentioned as influences include Patrick Rothfuss, George R. R. Martin, Joe Abercrombie, and Tamsyn Muir. [8]

Critical reception

Quicksilver received positive reviews from several publications. Marie Claire wrote that the novel is recommended "for those who like their slow-burn romances with plenty of quick banter and a healthy dose of spice." [15] Cosmopolitan stated that "This story raises our love of enemies-to-lovers to a whole different level." [15] Women's Health praised the novel's "diverse group of fantastical creatures and unique magic system." [15] First for Women compared the book favorably to Sarah J. Maas's A Court of Thorns and Roses series. [15] Screen Rant called the novel "impossible to put down." [15]
