Fourth Wing Books Top Amazon Kindle Best Sellers in 2025
The Empyrean series has surged 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' meteoric rise began with the publication of *Fourth Wing* in 2023, which gained immense popularity through Booktok. Since then, Rebecca Yarros' romantasy series has captivated a wide audience, blending fantasy and romance in a way that appeals to a broad spectrum of readers. The recent greenlighting of a *Fourth Wing* TV series by Amazon presents an opportunity for the Empyrean series to potentially surpass even the Harry Potter franchise in popularity, provided it capitalizes on this momentum effectively.
The viral nature of Yarros' writing is evident in how *Onyx Storm* has attracted a fresh wave of readers to the series. This success story is not limited to digital formats; the physical editions of the Empyrean series are also making waves.

The Empyrean series not only dominates the Kindle charts but also holds a strong position on Amazon's top-selling physical books list for 2025. Both the deluxe and standard editions of *Onyx Storm* are within the top 10, while *Fourth Wing* remains in the top 25. The only book to momentarily eclipse *Onyx Storm* is the new release from Suzanne Collins' Hunger Games series. However, with more readers discovering the series through *Fourth Wing*, *Onyx Storm* could reclaim its position as the top fiction book before the end of 2025.
