Eleven-year-old Brian Page spends every waking moment in the forest behind the house where he lives with his father. But forests are always deeper than anyone can know. Secrets are hidden in the eternal twilight of the trees. Those secrets emerge into light when Brian disappears in the forest, as his father did three decades before. His father, however, came home with no memory of the events in the depths of the forest. What has drawn Brian away? Will he emerge, shuddering and broken, as his father did, or will the forests close around him, as they have done so often before?
