Little Bee, Chris Cleave

Ok, this is a run right out and get it book. (The review site says there is an interview with the author, and notes for book clubs)
It is a dark story, that is also light hearted and funny, has wonderful prose, and alternates effectively between the two main narrators. The reviews also say not to reveal too much about the story, or the ending, but it does give it four and a half stars out of five, and says 91% of readers recommend it to their friends.
