If you are a historical fiction lover, especially WWII history, this book is amazing! So many WWII books are written of the war itself, from the points of view of the men on the frontlines; this, however, is one of the best books I've ever read from the perspective of the "women's war." The story is historically factual, and the fictional story is beautiful and heartbreaking. I felt such a range of emotions: anger, hope, resistance, fear, rage, love, and inspiration. I even had to break out the tissues, multiple times. Although fictional characters, their stories are so realistic that it makes you sob. The story of these two sisters surpasses this novel. It stretches into a real time of history where women aren't usually remembered, and it is exquisitely told. Kristin Hannah makes you feel their hope, despair, and love. She tells a story that has been mostly forgotten by history, a story left in the shadows- what happened to those who were left behind and how they managed to survive.
