The Tattooist of Auschwitz by Heather Morris

This is a pretty amazing story and the book is based on a true story - hard to believe. But then again, the whole thing is hard to believe.
I loved the book but thought that the end was a little weak. Not sure why. It's a true story so I can't dispute the ending. I guess I expected the author to "jazz it up" a bit. And he didn't....which was the right thing to do.
Therefore, I don't understand my reaction!
