A Maze of Death

I wouldn't say this is one of Dick's best books, certainly not up to the level of Do Androids Dream of Electric Sheep? or Valis. It's just a classic Dick tale, science fiction and psychological intrigue. A bunch of sub-par humans find themselves on an outpost on a new planet, they don't know what they are supposed to be doing there, and something is killing them. The ending is pulled out of a hat, but it's your standard P.K. Dick "reality isn't what we think it is" trick that we love him for. Lots of good Dick theology, not so much schizophrenia.
