Mythago Wood by Robert Holdstock - tpbk
Trade paperback format. Highly recommended.
Myth and Terror in the Forest Deeps
The mystery of Ryhope Wood, Britain's last fragment of primeval forest, consumed George Huxley's entire long life. Now, after his death, his sons have taken up his work. But what they discover is numinous and perilous beyond all expectation.
For the Wood, larger inside than out, is a labyrinth full of myths come to life, "mythagos" that can change you forever. A labyrinth where love and beauty haunt your dreams. . .and may drive you insane.
"This is a winning novel with a fine feeling for the interface between airy dreams and sweaty reality."--Publishers Weekly
