Hmmmm....I may have to read this book just because it sounds like the real life of someone I know.
A childhood friend's daughter has two white children, then had two biracial children with a man who was convicted of killing a woman and is somehow out on parole. She lives in one of the seedier areas outside DC and has an on again/off again relationship with the father of the two youngest. This books sounds like it parallels her life.
Anyway, I'm off download the sample and I'll let you know what I think.
