Slave Ship

Slave Ship is a 1956 short science fiction novel by American writer Frederik Pohl, originally serialized in Galaxy. The scene is a world in the throes of a low-intensity global war, which appears to be an amplified representation of the Vietnam War, in which the U.S. was just beginning to be involved. The plot involves telepathy, speaking to animals, and, in the last few pages, an invasion by extraterrestrials.
