I Am Margaret and gives it 5 claws!
"A caution to parents: There are some graphic scenes of torture that are not gratuitous but have a very clear purpose. Even so, very young readers and/or the faint-hearted might have trouble reading them. Older teens will find Margaret's story unforgettable and inspiring, and they will want to continue with the next book in the series."
This book is also found on the Catholic Teen Books website.
