Fourth Wing is a divisive fantasy novel that has garnered both passionate fans and harsh critics. While some readers praise its addictive plot and romance, others criticize its weak worldbuilding and clichéd writing. The story follows Violet, a young woman forced to train as a dragon rider at a brutal war college, as she navigates deadly challenges and a forbidden romance.

Iron Flame, the sequel to Rebecca Yarros's bestselling Fourth Wing, has received mixed reviews. Many readers found it highly entertaining with non-stop action, exciting plot reveals, and expanded world-building. The chemistry between protagonists Violet and Xaden remains strong. However, some felt the pacing was off, with repetitive elements and too many new characters. While most enjoyed the book overall, some found it didn't quite recapture the magic of the first installment.

Readers are generally enthusiastic about 'The Empyrean Series', praising its engaging world-building and character development. Many found the books highly addictive, finishing them quickly despite their length. However, some noted that 'Iron Flame' had pacing issues and repetitive themes compared to 'Fourth Wing'. Despite these criticisms, most readers are eagerly anticipating the next installment.
