Query: A worthwhile read

This book mostly reads like a collection of short stories in that each chapter or two can stand alone--but there is a more or less continuous thread connecting them. This is a must-read before getting to the latest (? last) of the Keller stories, Hit and Run. Block is always a good read, sometimes a great read, so I recommend it highly to all his fans.
