Rebecca Yarros's Empyrean series continues its meteoric rise, with the recent release of Onyx Storm propelling all three books to the top of Amazon's 2025 Kindle bestsellers list. The series' popularity exploded in 2023 following the release of Fourth Wing, largely thanks to the viral sensation on BookTok. This phenomenal success has seen the Empyrean series dominate numerous bestseller charts. The influx of new readers following Onyx Storm's release is a testament to Yarros's captivating blend of fantasy and romance, appealing to a wide readership. With an Amazon-produced Fourth Wing TV series now in the works, the Empyrean series has the potential to surpass even the Harry Potter franchise in popularity.
The series' success isn't limited to the digital realm. The Empyrean books also feature prominently on Amazon's 2025 top-selling physical books list. Both the deluxe and standard editions of Onyx Storm are in the top 10, while Fourth Wing remains within the top 25. Only the recent release of Suzanne Collins' new Hunger Games novel has knocked Onyx Storm from the number one fiction spot. However, with the continued influx of new readers discovering the series through Fourth Wing, this ranking could easily shift again before the year's end.
