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

The Empyrean series has soared to new heights with the 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' initial surge in popularity came with the 2023 release of *Fourth Wing*, largely fueled by the Booktok community. Since then, this captivating romantasy series has not only dominated best seller charts but also captured the hearts of a diverse audience with its perfect blend of fantasy and romance.

Rebecca Yarros' storytelling prowess is evident in the viral success of *Onyx Storm*, drawing in countless new readers to the series. With a *Fourth Wing* TV series now greenlit at Amazon, the Empyrean series stands poised to potentially eclipse the fame of the Harry Potter franchise, provided it capitalizes on this momentum effectively.

While the Empyrean series is a powerhouse on the Kindle charts, it also commands a significant presence on Amazon's top-selling physical books list for 2025. The deluxe and standard editions of *Onyx Storm* are nestled within the top 10, with *Fourth Wing* not far behind in the top 25. The recent release of Suzanne Collins' new Hunger Games book has nudged *Onyx Storm* to the second spot on the fiction list, but with the influx of new readers starting with *Fourth Wing*, this could shift yet again before the year ends.
