"Instead of changing the planet to fit the man, we change the man to fit the planet..."
In the middle-distant future, Andrew Blake, discovered huddled inside a capsule orbiting a remote star, is brought back to Earth suffering from total amnesia. Over 200 years old, he thinks and acts like a man, but becomes frighteningly aware of two alien beings that lurk within his body - a strange biological computer, and a wolf-like creature. Dangerously possessed, Blake breaks out of the hospital to look for his past. What he discovers is a world that has no place for him, filled with telepathic brownies, talking houses, and a government that wants to get rid of him. Permanently. One of Simak's most provocative novels brings to life exciting ideas and themes just as philosopically and scientifically relevant today as the day he wrote it.
