To Your Eternity

An orb is dropped onto Earth by a being who never explains itself. The orb can take the shape of anything that stimulates it, and it cannot die. It becomes a rock, then a wolf, then a boy. The boy gets a name from the only human he meets — Fushi — and discovers that grief and curiosity look the same from the inside. The series follows him through centuries, picking up the lives, languages, and bodies of the people he loses, and slowly cohering into the kind of person who can do something about the predators chasing him.
