What Is the Empyrean Series About?

Before diving into the series, a friend recommended "Fourth Wing" to me, describing it as "Like the Harry Potter books, but with dragons." While that comparison holds in the early stages, the series soon takes a turn reminiscent of the Twilight saga. It's a magical, fantasy romance novel that delves into graphic details.

The story centers on Violet Sorrengail, a seemingly fragile young girl thrust into the perilous world of dragon riders by her powerful mother. As Violet navigates her challenges and survives the academy, she grapples with complex emotions about her mother, a former friend, and a boy she believes wants her dead. Amidst this, deeper secrets about the dragons and her world unfold, positioning Violet at the heart of an epic romance and a larger mystery.
