I've read three enlightening books recently. Actually, I haven't finished Sarah's Key by Tatiana De Rosnay. The other two books are Little Bee by Chris Cleave and The Help by Kathryn Stockett.
If you want light reading, these books aren't for you. Every one of these books tells a story of the horror that humans have carried out against other human beings. I think we need to know and we need to remember even when the memories are painful.
All of these books are extremely well-written. I recommend them to all of you. In spite of the emotionally shocking elements, I'm quite certain you'll be glad you invested your reading time in them.
