V.E. Schwab's 'Vicious' is a compelling anti-superhero novel that will appeal to readers who enjoy morally gray characters and dark urban fantasy. The story follows Victor Vale and Eli Ever, former college roommates whose friendship implodes after they discover how to gain supernatural abilities through near-death experiences. Ten years later, Victor escapes from prison seeking revenge against Eli, who has become a self-appointed judge executing other 'ExtraOrdinaries' (EOs) in the name of God.

Schwab excels at crafting complex, unlikable protagonists. Neither Victor nor Eli is truly heroic—Victor is calculating and vengeful, while Eli is a religious zealot convinced of his own righteousness. The author doesn't ask readers to root for either character so much as understand their motivations, making this a refreshing departure from traditional good-versus-evil narratives. The supporting cast, including the fierce Sydney and loyal Mitch, adds emotional depth to what could have been a purely cerebral revenge story.

The novel's structure jumps between timelines, gradually revealing how the friendship deteriorated and building toward their inevitable confrontation. This pacing works well, though some readers may find the frequent time shifts initially disorienting. Schwab's prose is sharp and atmospheric, creating a convincingly gritty urban setting where superpowers feel more like curses than gifts.

The book's greatest strength lies in its exploration of power, corruption, and the thin line between hero and villain. Schwab asks uncomfortable questions about who gets to decide what's right and whether good intentions justify terrible actions. The themes of friendship, betrayal, and the corrupting nature of power give weight to the supernatural elements.

However, 'Vicious' isn't for everyone. Readers seeking traditional heroes or clear moral victories should look elsewhere. The dark tone and morally ambiguous characters may frustrate those wanting straightforward fantasy adventure. Additionally, while the character development is strong, some plot elements feel underdeveloped, particularly the mechanics of how EO powers work.

This book will particularly appeal to fans of dark urban fantasy, superhero deconstructions, and character-driven narratives. It's perfect for readers who enjoyed 'The Boys' or other media that examines the darker side of superpowers, though it's less graphic and more psychological in its approach.
