The Ashes and the Star-Cursed King (2023) is the sequel to The Serpent and the Wings of Night (2022). It is the final installment in the Nightborn Duet, which follows the romance of Oraya and Raihn, members of the House of Night. The Nightborn Duet is the first part of Crowns of Nyaxia, a planned 6-book series consisting of three duologies within the same fantasy world. Each duology follows one romantic coupling while simultaneously developing an overarching plot line that spans all six installments. Books three and four of the Crowns of Nyaxia series—the Shadowborn Duet—will follow a couple from the House of Shadow, while books five and six—the Bloodborn Duet—will explore the House of Blood.

The series also includes a novella and a full-length standalone romance which offer more insight into the world and its characters. Six Scorched Roses (2023) is a standalone novella that occurs just after the events of The Serpent and the Wings of Night. It depicts the romance between Lilith and Vale, two characters who come into play during The Ashes and the Star-Cursed King. Slaying the Vampire Conqueror (2023) is a standalone novel following Sylina, an assassin sent to kill a vampire lord named Atrius, whom she falls in love with instead.
