He wakes up in the world of his favorite game, Eternal Chronicle III—as Cain, the most despicable minor villain. His new body is weak. His new sister, Sophia, fears him. The servants wish him dead. And inside his mind, the original Cain waits to take control. He must prove he can change. Softly. Like it mattered. Even if no one believes him.)
