The Green Isle of the Great Deep — Neil M. Gunn

This is a magical tale of the adventures of Young Art and Old Hector - the boy and the old man - in a land between life and death. When the two fall into the depths of a salmon pool, they wake to find themselves in a bright yet strangely brittle countryside, not unlike their own, but with a terrifying nightmarish quality. As in all Gunn's works, the mythology unfolds in real landscapes among living people, all of them drawn from his own rich childhood on the Moray Firth.
