It has many names: Bigfoot . . . Yeti . . . Sasquatch.

But whatever it is, it’s out there in the woods and leaving a trail of blood and severed heads behind it.

For John Moon, a half-mad Indian, it is a spirit that holds the key to his inner self. He worships its power and he’ll kill to protect it. Desperate, exhausted, half-starved, Moon will follow it wherever it goes.

For Raymond Jason, killing it has become an obsession. He was the only survivor of a hunting trip to the Rockies where the hunters became the monster’s prey. Now he is determined to track the creature down and destroy it.

But when the two men finally corner their quarry they set loose a flood of terror and destruction that may leave no survivors ...

This long-awaited reissue of Thomas Page's Bigfoot classic The Spirit (1977) features a new introduction by Grady Hendrix and cover art by paperback horror legend Tom Hallman.
