The Fourth Wing Books are Dominating Amazon's Kindle Best Sellers List in 2025 So Far

Rebecca Yarros's Empyrean series continues its meteoric rise, with all three books—Fourth Wing, Iron Flame, and the recently released Onyx Storm—currently dominating Amazon's 2025 Kindle best-seller list. The series' popularity exploded in 2023 following the initial publication of Fourth Wing, largely propelled by the power of BookTok. This phenomenal success has propelled the Empyrean series to the top of 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, resonating with a diverse readership. With an Amazon-produced Fourth Wing TV series now in the works, the Empyrean series has the potential to achieve even greater heights, potentially surpassing even the Harry Potter franchise.

The series' success isn't limited to the digital realm. The Empyrean books also hold prominent positions on Amazon's 2025 best-selling physical books list. Both the deluxe and standard editions of Onyx Storm are within the top 10, while Fourth Wing remains a top 25 seller. Only the recent release of Suzanne Collins' new Hunger Games novel has momentarily relegated Onyx Storm to the number two spot in fiction. However, given the ongoing influx of new readers discovering the series through Fourth Wing, this ranking could easily shift again before the year's end.
