A boy climbs a tree, scrambles among the branches, moves from one tree to another, and decides he will never come down. The author of this book has taken this simple image and pushed it to its extreme consequences: the protagonist spends his entire life in the trees, a life far from monotonous, indeed full of adventures, and far from being a hermit, while always maintaining a minimal but insurmountable distance from others. The result is a book that defies precise definition, just as the protagonist leaps from one oak branch to another and remains more elusive than a wild animal.
