this book was so sad, but at the same time it was by far one of the best books about the holocaust ive read. its hard to choose whether prision b-3807 (sorry if i got the numbers mixed up) or this book is better. between shades of gray really changed my perspective on life and made me realize how lucky i am to be living today. i would highly suggest this book to anyone ages 14 and older (i am 14) because it is definitely for more mature audiences. one of the best.
