My Mother's Secret - J.L. Witterick

As this book's subtitle helpfully explains, this book is A Novel Based on a True Holocaust Story, the story of Franciszka Halamajowa and her daughter, Helena, who were able to save 15 Jewish people (and a defecting German soldier) by hiding them in and around their home in Nazi-occupied Poland during World War II. The writing is clear and easy to read, and the story is told Rashomon-style, so we see the events from differing points of view. This was a deceptively simple read that told an amazing story. Recommended.
