Fourth Wing Books Top Amazon's Kindle Best Sellers in 2025

The Empyrean series has seen a meteoric rise in popularity, with the latest installment, Onyx Storm, released earlier this year propelling all three books to the top of Amazon's Kindle best sellers list for 2025. The series' surge in readership began with the debut of Fourth Wing in 2023, which gained significant traction on Booktok. Since then, Rebecca Yarros' romantasy series has captivated a wide audience, consistently dominating bestseller charts.

The release of Onyx Storm has not only attracted new readers but also highlighted the viral appeal of Yarros' storytelling, blending fantasy and romance in a way that resonates with a broad readership. The excitement surrounding the series has further escalated with the announcement of a Fourth Wing TV series at Amazon, positioning the Empyrean series to potentially surpass even the Harry Potter franchise in popularity if it continues to leverage its momentum effectively.

Both the deluxe and standard editions of Onyx Storm are firmly entrenched in Amazon's top 10 best-selling physical books for 2025, with Fourth Wing also holding strong in the top 25. The only recent challenge to Onyx Storm's dominance came with the release of Suzanne Collins' new Hunger Games book, which briefly pushed it to the second spot on the fiction list. However, with more readers discovering the series through Fourth Wing, Onyx Storm could reclaim the top position before the year ends.
