A thrilling young adult dystopian science fiction novel by Michael Grant. Published in 2018, it is the eighth book in the Gone and the second installment of the Monster Trilogy, which continues the story four years after the original Gone saga.

Four years have passed since the terrifying events in the FAYZ (Fallout Alley Youth Zone). Although the mysterious dome is gone, its legacy lives on. The alien organism responsible for the catastrophe has spread beyond Perdido Beach, creating terrifying superpowered monsters that threaten civilization. Governments struggle to contain the chaos as military forces battle increasingly dangerous mutations.

Amid this crisis emerges a terrifying new antagonist: Dillon Poe, a bitter outcast gifted with the horrifying ability to control anyone through the sound of his voice. Once mocked and ignored, Dillon now possesses the power to command thousands of people, turning entire cities into weapons of destruction. Standing against him are familiar heroes including Dekka Talent, Shade Darby, Cruz, Malik, Armo, and several new superpowered characters who must decide what truly separates heroes from villains.

As the conflict escalates, the novel explores themes of power, revenge, morality, identity, and the corrupting influence of extraordinary abilities. Packed with brutal action, shocking twists, and emotional character development, Villain builds toward an explosive finale that leads directly into the concluding novel, Hero.
