What are you reading?

I'm reading my Dad's letters from the time he went into the Army in1943 till he arrived home in 1945. He was the only survivor of his mortar squad when his unit was overrun in the winter during the Battle of the Bulge. He was trapped in his foxhole for ten days with Germans all around him. He was lucky.
My Vietnam memoir is based on the letters I sent home from my war and that he saved for me. My sister gave me a box with his letters last week.
I'm making notes as there may be another book in me.
