Intertwined

Most sixteen-year-olds have friends. Aden Stone has four human souls inside him: One can time-travel. One can raise the dead. One can tell the future. And one can possess another human. With no family and a life spent in and out of institutions, Aden and the souls have become friends. But now they're causing him all kinds of trouble. Like, he'll blink and suddenly he's a younger Aden, reliving the past.
Or he'll walk past a total stranger and know how she's going to die. He's so over it. All he wants is peace. And then he meets a girl who quiets the voices. Why? Mary Ann Gray is his total opposite. For her sake, he should stay away. But it's too late.
