THE BOOK OF PTATH is a fantasy novel published in 1943.
The setting is Earth, 200 millions years from now. Peter Holworth wakes up in a state of amnesia. Little by little, he remembers that he's died in a battle during WWII and remarks that a second personality is living now in his body. In fact, a being named Ptath, is trapped in Holworth's body. Ptath had decided a long time ago to be incarnated in the body of a series of common people in order to learn empathy, a feeling that could help him rule his country Gonwonlane. But, during Ptath's absence, a being named Ineznia has seized the reins of power and begun a hunt in order to catch a still weak Ptath. Both have the ability to leave their carnal body and secretly pass from people to people by squatting their mind. Soon, as Ptath is recovering, a huge battle is in the air, involving the armed forces of the three continents.
