Bestselling author Rebecca Yarros is returning to her romance roots with her next novel, People magazine reports.

Yarros, who dominated the bestseller charts with her Empyrean series of “romantasy” novels, will publish Variation with Amazon imprint Montlake this fall. The novel follows Allie, a dancer at loose ends after sustaining an injury that ends her career, who meets a niece, given up for adoption long ago. The niece leads her to reconnect with Hudson, her first love.

Yarros wrote several romance novels, including The Last Letter, Great and Precious Things, and The Things We Leave Unfinished, before publishing Fourth Wing, the first volume in her Empyrean series, in 2023.

Fourth Wing, which tells the story of a student at a college for dragon riders, became a hit on TikTok’s BookTok community; the novel’s success on that platform led it to national bestsellerdom. The book’s sequel, Iron Flame, was published six months later; it too became a huge hit. The third novel in the series, Onyx Storm, is slated for publication next January.

Last October, it was announced that the Empyrean series will be adapted as a television series by Amazon MGM Studios and Michael B. Jordan’s production company, Outlier Society.

Yarros told People that she is “thrilled” to be publishing Variation with Amazon. "They're such a supportive, incredible team to work with, and I can’t wait for readers to fall in love with Allie and Hudson’s story and the years of family secrets that surface when these two collide after years apart,” she said.

Variation is scheduled for publication on Oct. 8.
