Evelyn Pluto Murphy has spent her entire life seeing things no one else can. So has her best friend, Percy Jackson. Monsters hiding behind human faces. Myths that refuse to stay buried. Shadows that move when they shouldn't. Adults call it imagination. Teachers call it trouble. But when a routine school trip turns violent and a trusted teacher reveals herself to be something inhuman, Evelyn and Percy are forced to face the truth-the ancient gods are real, their stories never ended, and the two of them are no longer invisible. Betrayed, frightened, and armed with strange weapons they don't understand, Evelyn and Percy are pulled into a world where loyalty is tested, danger is constant, and survival depends on choices far beyond their years. As monsters close in and secrets unravel, Evelyn must confront the question she's avoided her whole life: why her? Because some children are born ordinary. And some are born carrying the weight of myths that never truly died.
