The Fighter of Auschwitz: The incredible true story of Leen Sanders who boxed to help others survive
I found the writing style quite jarring to begin with, and wasn't sure I was going to get through it, but I'm so glad I did as it was a highly moving story that had me fighting back tears by the end. Thoroughly recommended.
