The Land That Time Forgot

The first book in his Caspak trilogy The Land That Time Forgot is a fantasy book by American author Edgar Rice Burroughs. The first chapter of the book which takes place during World War I is framed by the discovery of a manuscript recounting the plot from a thermos off the shore of Greenland. It claims to be the story of Bowen J. Tyler an American passenger who was sunk by the German U-boat U-33 in the English Channel in 1916. By the time the saboteur is discovered the submarine has already entered the Antarctic seas after being led off course. A group of beast men assault the castaways and capture Ahm a Neanderthal Man. They discover that the island's indigenous name is Caspak. They find oil which they intend to convert into U-33 fuel. Tyler departs from the other survivors to find Lys and save her. The many bands of near-human primitives each of which represents a distinct stage of human development engage in a series of adventures.
