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

The Empyrean series has taken the literary world by storm with its latest release, Onyx Storm, earlier this year. All three books in the series are currently dominating Amazon's Kindle best sellers list for 2025. The series gained significant traction with the release of Fourth Wing in 2023, largely fueled by the viral sensation on Booktok. Since then, the romantasy genre blend has captivated a wide audience, propelling the series to the top of various bestseller charts.

The immense popularity of Onyx Storm has introduced many new readers to Rebecca Yarros' enchanting world, showcasing the viral appeal of her storytelling. With the perfect mix of fantasy and romance, the series has the potential to attract an even broader audience. With the announcement of a Fourth Wing TV series in development at Amazon, the Empyrean series is poised to possibly surpass even the Harry Potter franchise in popularity if it continues to play its cards right.

The Physical Editions Are Popular Too

While the series dominates 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 are within the top 10, and Fourth Wing remains in the top 25. The only recent release that has managed to edge out Onyx Storm from the top spot is Suzanne Collins' new Hunger Games book. However, as more readers discover the series starting with Fourth Wing, we might see Onyx Storm reclaim its position before the end of 2025.
