If you've read Joe Sacco's other works of reportage, Palestine and Safe Area: Gorazde, you'll know what to expect from this; tales of humanity in war zones, told with a light touch without sparing the gruesome details.
If you haven't read those books, I suggest you read them first and this after.
This book is a collection of miscellaneous material, with one 'novella' length story - The Fixer - and a few shorter. The titular story is about the man who helped the author make contacts and find stories when he was in the former Yugoslavia, and raises questions about his own story, without ever losing sight of him as a person.
I debated whether to give this four stars or five, but settled on four only because the authors other reportage books are stone-cold fives, and this is not quite as complete. But if you enjoyed those, you'll love this just as much.
