For the first twelve years of Arrow’s life, he grew up as the only human in a lush, magical rainforest that’s closed off from the rest of the world. He was raised by the Guardian Tree, the protector of the forest, which uses the earth’s magic to keep it hidden from those who have sought to exploit and kill it. But now the magic veil is deteriorating, the forest is dying, and Arrow may be the only one who can save it.

Arrow never saw another human until one day, a man in a small airplane crash-lands in the forest. Then, a group of children finds their way in, escaping from their brutal, arid world where the rich live in luxurious, walled-off cities and the poor struggle for survival.
