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 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 power of BookTok. This captivating romantasy series has since conquered numerous bestseller charts. The success of Onyx Storm in attracting a wave of new readers is a testament to Yarros's ability to blend fantasy and romance, captivating a wide audience. 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.

Physical Editions Remain Popular

The Empyrean series isn't just dominating the Kindle charts; it's also a major player in Amazon's top-selling physical books list for 2025. Both the deluxe and standard editions of Onyx Storm are in the top 10, while Fourth Wing remains in the top 25.

Only the recent release of Suzanne Collins' new Hunger Games book has knocked Onyx Storm from the number one spot for fiction. However, with the ongoing influx of new readers discovering the series through Fourth Wing, this ranking could easily shift again before the year's end.
