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' surge in popularity began with the release of "Fourth Wing" in 2023, fueled significantly by the viral power of BookTok. Since then, this captivating romantasy series has consistently dominated bestseller charts, captivating a wide audience with its blend of fantasy and romance.
The release of "Onyx Storm" has not only attracted new readers but also highlighted the viral appeal of Rebecca Yarros' storytelling. The perfect mix of fantasy and romance has enchanted a diverse readership. With the announcement of a "Fourth Wing" TV series in development at Amazon, the Empyrean series is poised to potentially surpass even the iconic Harry Potter franchise in popularity, provided it capitalizes on this momentum effectively.

While the Empyrean series continues to dominate the Kindle charts, it also holds a strong position on Amazon's top-selling physical books list for 2025. Both the deluxe and standard editions of "Onyx Storm" rank within the top 10, with "Fourth Wing" maintaining a spot in the top 25. The recent release of Suzanne Collins' new Hunger Games book has temporarily pushed "Onyx Storm" to the second spot on the fiction list. However, with an influx of new readers discovering the series through "Fourth Wing," we might see a shift back to the top before the year ends.
