As the story unravels, you learn that Toby lives in the Tree but his family was forced out of the Upper Branches to the bleak Lower Branches because his dad was a scientist who refused to reveal a secret that could destroy the lives of them all.
A fascinating fantasy world about tree people with nice allegories to earth. When you first meet Toby, he is on the run--from his former friends, life, everything. He doesn’t even know where his parents are.
