What Is the Empyrean Series About?

If you haven't yet read *Fourth Wing* or any other title in the *Empyrean* series, you might be curious about what makes Rebecca Yarros' novels so wildly popular—comparable to the cultural impact of *The Hunger Games* and *Twilight*. In essence, the series blends beloved fantasy tropes with fresh storytelling: think dragons reminiscent of *Eragon*, academy-life drama similar to *Harry Potter*, and emotional romance akin to *Twilight*.

The story follows Violet Sorrengail, a physically frail but fiercely determined young woman who is pushed by her formidable mother into a brutal dragon rider academy. As she struggles to survive in a world built for the strong and ruthless, Violet must also navigate complex relationships—with her estranged childhood friend, a brooding cadet who seems to despise her, and a mysterious dragon bond that may hold the key to unlocking her true potential. Meanwhile, hidden forces are at play in her world, drawing Violet into a larger conflict and a sweeping romantic journey that could change everything.
