Less than thrilling account of spacefarer Olof Carlsen battling alien energy vampires who can move from one body to another. After an early encounter with one such creature, in the body of a beautiful woman, Carlsen finds himself psychically linked to her, with new powers of his own to drain the energy of others as well as read their minds, using his abilities principally to cheat on his wife. Perhaps it's not as bad as all that, but this is a slow-mover that talks a good game -- linking criminality (particularly in the sexual arena) to vampirism -- but fails to demonstrate it with any meaningful action. The book, says Wilson, is "indebted" to A. E. van Vogt's short story "Asylum." Tobe Hooper (The Texas Chainsaw Massacre) directed the adaptation in 1985 as Lifeforce.
