It's been a long time since a book has kept me up until 4 a.m., but this one did just that. I love a good book that alternates between the past and the present and keeps you in suspense along the way. The ending was a little too neat and tidy for me, which kept me from giving it a full five stars (I think an epilogue would have served the book better) but if you enjoy WWII fiction, you will enjoy this.
This was an interesting book, told from two perspectives, a young widowed mother in present day, and a young single woman during WWII. In 2012 a seven year old boy has terrible nightmares, and awakes with stories of Nazis and spies. Through a series of clues the mother matches the stories in the nightmares to the young woman in the 1940's who had a secret boyfriend who was a Nazi spy.
