She has 3 books listed on Kindle but not an autobiography. They’re all novels. Can you please tell me the title of her autobiography? Maybe I can get it on Amazon.
My favorite is her autobiographical work from 1959.
I should warn you that she was trained as a nurse, not a sniper. But she did well in firearms training and had some experience described in the book shooting at Germans. Here is the link to used editions of the out of print book on Amazon. They start at $5.94 + $4.00 shipping.
