Author:Kristen Update:May 26,2025

The Empyrean series has rapidly risen to fame, propelled by its unique premise and a viral boost from TikTok. "Fourth Wing," the series' inaugural book by Rebecca Yarros, has maintained its spot on Amazon's top-sellers list since 2023. The anticipation for the latest installment, "Onyx Storm," is palpable, with preorders securing the number two spot on Amazon's best-seller list in 2024.

Mark your calendars for the official release of "Onyx Storm" on Tuesday, January 21. Currently, Amazon is offering discounted preorders for this eagerly awaited book.

What Is the Empyrean Series About?

Before diving into the series, a friend described "Fourth Wing" to me as "Harry Potter, but with dragons." While this comparison holds true in the early stages, the narrative soon evolves into something more akin to the "Twilight" series, evolving into a deeply immersive, fantasy romance novel with graphic details.

The story 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 complex emotions about her mother, an old friend, and a boy she believes wishes her harm. Amidst an epic romance, Violet uncovers deeper secrets about the dragons and her world, placing her at the heart of unfolding mysteries.
