Good fantasy - and that includes science fiction - takes off from the known for its flights into the new. Cliff Simak was a master of the art. His known was the rural Midwest that he loved. His new could reach to the ends of space and time, but never beyond reality. Even his cosmic aliens always had half human dimensions that made them believable. I loved him, as so many did, for his unfailing warmth and a wit that was keen but never cruel. I heard from him often during the painful time after his wife's death. His own death touched me deeply, and I'm happy to see him remembered with this collection of his best-loved stories.
