The Empyrean series has taken the literary world by storm, with the recent release of Onyx Storm earlier this year propelling all three books to the top of Amazon's Kindle best sellers list for 2025. The series first gained momentum with the release of Fourth Wing in 2023, which quickly became a sensation on Booktok. Since then, this captivating romantasy series has not only dominated the Kindle charts but has also found its way onto most best seller lists.
The viral success of Rebecca Yarros' writing, evident with the release of Onyx Storm, has attracted a diverse readership, perfectly blending fantasy and romance to captivate a wide audience. The announcement of a Fourth Wing TV series in development at Amazon adds to the excitement, positioning the Empyrean series to potentially surpass the popularity of the Harry Potter franchise if it continues to resonate with fans.

The Empyrean series doesn't just dominate the digital realm; it also commands a significant presence on Amazon's top-selling physical books list for 2025. Both the deluxe and standard editions of Onyx Storm are ranked within the top 10, while Fourth Wing maintains a strong position within the top 25. The only book to have recently overshadowed Onyx Storm is Suzanne Collins' latest addition to the Hunger Games series. However, with an increasing number of new readers discovering the series through Fourth Wing, Onyx Storm might reclaim its spot as the top fiction book by the end of 2025.
