Half Blood Blues by Esi Edugyan

This book masterfully tells the story of a jazz band just before and during the Second World War. The trumpet player, Hieronymous Falk, is a prodigy--worthy to play with Louis Armstrong, but even in Paris he's having visa problems (his German nationality isn't helping matters any) as the band tries to head for the United States. Jealousies about musical talent and a woman, and the pressures of living in occupied Paris all come to a boil as the band cuts a wonderful record turning Nazi propaganda on its head. I loved the way this book played out--moving between (something close to) the present day and the past, with a narrator just self-interested enough not to be entirely trusted. It's a fresh and engaging World War II story.
