Toby Lolness may be just one and a half millimeters tall, but he's the most wanted person in his world — the world of the great oak Tree. Toby's father has made a groundbreaking discovery: the Tree itself is alive, lowing with vital energy, and there may even be a world beyond it. Greedy developers itch to exploit this forbidden knowledge, risking permanent damage to their natural world. But Toby's father has refused to reveal his findings, causing the family to be exiled to the lower branches. Only Toby has managed to escape — but for how long? And how can he bear to leave his parents to their terrible fate?
