This wasn't your typical WWII book set in France. For starters, the plot lines toggled between WWI and right after WWII.

There was a lot I enjoyed about this book:
-One storyline centered around strong women serving as spies in WWI
- The other storyline featured a pregnant, unwed protagonist who was good at math - and a surly old woman who drank whiskey, carried a Luger and swore like a sailor
- The element of mystery - first a quest to find a missing cousin, then to settle a score

There were a few things that didn't work for me:
- I'm not familiar with pregnancy statistics during this time, but the number of single women who get pregnant in this book seems improbable. The plot could've worked without that unlikely coincidence. (Though sex is treated pretty casually in this book, so if you accept that independent women during this time would've been bedding whoever they wanted, then ok - maybe everyone WOULD be pregnant. Both assumptions seem far-fetched.)
- Why would you write a book about a strong, independent woman - and then still feel compelled to have her fall in love? C'mon!

Overall - fun (and dark) little adventure through France, if you can get past the contradictions and coincidences.
