A Maze of Death is a 1970 Philip K. Dick chronicle of fourteen strangers who are brought to an alien world for an unknown purpose. They are gradually and mysteriously killed off a lá Agatha Christie's And Then There Were None. The most notable aspect of this book is the concepts of religion that it introduces. The characters in the book unanimiously believe in gods who live on distant planets and can be reached through radio-transmitted prayers. Dick uses most of the novel to explore and develop the religion that he has created.
A Maze of Death uses science fiction as a vehicle for theology. Dick examines the creation of a world with God as a replacement for the meaningless world in which his protagonists live. Highly recommended for any interested in Dick's thoughts on religion.
