First They Killed My Father: A Daughter of Cambodia Remembers by Loung Ung is a memoir that was recommended to me by a former work colleague who never fails me on her good choices. I listened to this one on Libby. It is a sad and difficult story to hear/read, but was very interesting. I enjoyed it, but it was a long one that took many hours to listen to. Perhaps reading the book would have been faster. I did enjoy learning the story, but think the format was not the perfect one for me.
