I'd heard a great deal of talk about this book and was eager to read it. The story itself was moving -- a story of what a mother does during the Holocaust to ensure she and her daughter survive, and how those decisions impact both their lives. There were parts of the book I found to be graphic, and I wasn't prepared for that. A great read, and good for book club discussions, but you should be aware of the graphic nature of certain parts, so I'd not recommend for teens or young adults.
It was a compelling read about the horrors of the Holocaust and the choices one makes to come out alive. I agree with the other reviewer that it is not suitable for teens without discussion. Blum has a gift of storytelling and it was easy to get lost in her words.
