'Devil's Tor', first published in 1932, is the undoubted masterpiece of David Lindsay. Many of the extraordinary and disturbing themes of his first and most famous work, 'A Voyage to Arcturus' (1920), are explored more deeply and expressed more clearly in this book. The story describes the experiences and mental processes of various people drawn by an active Fate to Devil's Tor, a minor Dartmoor height. Lives are transformed, shattered and ended by forces that can remake stars and galaxies. Nowhere in printed English is the working of the Unseen in living minds more vividly drawn than in David Lindsay; and nowhere in Lindsay more magnificently than in 'Devil's Tor'.

The cover shows a drawing of the labrus, the Minoan double-axe, which features in the book as a sign that the object so marked is sacred to the Great-Mother.
