Before embarking on the Empyrean series, a friend likened "Fourth Wing" to "the Harry Potter books, but with dragons." While this comparison holds true initially, the series soon veers into a territory reminiscent of the Twilight saga. It's a magical, fantasy romance that delves deeply into graphic details.
The narrative follows Violet Sorrengail, a seemingly delicate young woman coerced by her influential mother into attending a perilous academy for dragon riders. As Violet navigates her vulnerabilities and strives to survive, she grapples with her feelings toward her mother, an old friend, and a boy she suspects wants her dead. Amidst this, the dragons and her world harbor secrets that place Violet at the heart of an unfolding epic romance.
