Excellent book.  Extremely funny (not sure if that was his intention or not, but it was).  I love the way Simak took ordinary things, like bowling balls and dolls and dogs, and turned them into things not so ordinary.  The book flows completely from beginning to end (although the end is rather abrupt).  Parker and Joy almost made alien hunting seem fun!

 

Annotation

Andrew Blake is discovered huddled inside a capsule on a remote star and is brought back to earth. Over 200 years old and suffering from amnesia, Blake seems normal until he becomes aware of two alien beings who lurk inside his body. Dangerously possessed, Blake breaks out of the hospital to look for his past. "First-class entertainment."--Sunday Times.

My take
This was my first book by Simak and I love his writing style.  He creates beautiful images without boring me and without losing the story (like some authors seem to do when they get descriptive).  The ending was so shocking I actually sat up and gasped.  An excellent book about a man from space returning "home."
