The Empyrean series has rapidly gained popularity in recent years, fueled by its captivating premise and viral success on TikTok. Fourth Wing, the series debut, has maintained a spot on Amazon's bestseller list since 2023, while preorders for Rebecca Yarros' latest installment, Onyx Storm, ranked as Amazon's #2 top-selling title in 2024.
Onyx Storm officially launches on Tuesday, January 21, with discounted preorders available. First-time readers can also access the initial two books free through Kindle Unlimited for a limited time.

Initially described to me as "Harry Potter with dragons," Fourth Wing evolves into something closer to Twilight with fantasy elements and explicit romantic content. This magical coming-of-age romance blends danger, dragons, and complex relationships.
The narrative centers on Violet Sorrengail, a seemingly frail protagonist compelled by her formidable mother to join a lethal dragon rider academy. As Violet navigates physical challenges and emotional turmoil involving family, friendships, and romantic tension, she uncovers hidden truths about her world's dragon legacy—all while developing an intense love story.
