New.
B Format.
ALDER has always lived in his cozy little house in Southern California. And for as long as he can remember, the old walnut tree has stood between his house and the one next door. That is, until a new family moves into the neighboring house and cuts it down.
OAK doesn't understand why her family had to move to Southern California. She has to attend a new school, find new friends, and live in a new house. And now a strange boy next door won't stop staring at her, like she did something wrong moving here in the first place.
As Oak and Alder start school together, they can't imagine ever becoming friends. But the two of them soon discover a series of connections between them - mysterious, possibly even magical puzzles that can't put together. At least not without each other's help.
