"The Lost - a Search for Six of Six Million" by Daniel Mendelsohn, Harper Collins 2007
ISBN 978-0-00-725193-3
The situation in Bolechow, just south of Lviv, before and during WWII would probably have been very similar.
I've read this excellent book a couple of times. It's a mixture of family history research, with a lot of legwork in Europe, and first-hand testament regarding life and death in Bolechow before, and during, the occupation. I'm sure I'll read it yet again one day.
