10-11 is when you start to learn about sexual interactment. This book definetly has that! I am actually 10, and I read it... Loved it! I'm mature for my age, so I was aloud to read it... But other than that, I LOVED that book! It has a happy-sad mixed ending, and I cried. It showed that, to pass through life as a happy human, you have to let go of death. Anyways, loved it, cherished it!
