This book is the story of lost girls who worked as secret agents in WWII. It’s an enjoyable historical fiction book and I was captivated by the main storyline and wondering what happened to these girls. That being said, the story was a bit predictable and I wasn’t completely satisfied with the ending . I did love the character development of the three central women who narrate the story. The time periods jump but it’s easy enough to follow, and the action and adventure is always high. I felt like there were no low points in the storyline. How the women come to terms with their disadvantages and learn to be strong and brave makes an inspiring read. I recommend this for historical fiction lovers.
