Intertwined

Most sixteen-year-olds have friends. Aden Stone has four human souls living inside him:
One can time-travel.
One can raise the dead.
One can tell the future.
And one can possess another human.
With no other 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. One wrong move, and he'll change the future. Or he'll walk past a total stranger and know how and when she's going to die.
He's so over it. All he wants is peace.
