There Must Be Something in the Water

There must be something in the water.

I keep stumbling upon books featuring the World War II experiences of women: books about Jewish women trying to escape occupied Europe, books about female resistance fighters, books about female spies who worked behind enemy lines, etc. There is even one slightly different book about the inspiration a female Afghanistan War veteran finds by reading about a woman who disguised herself as a man in order to fight for the Union during the American Civil War. The plots are so similar that it's becoming harder and harder to keep track of which title goes with which plot.

But publishers aren't satisfied just to flood the market with plots I can barely keep straight. Take a look at the covers of these same books. Does anyone really believe that it's a coincidence that even the covers are hard to keep straight? My theory is that publishers realize there is probably a good market for two or three of these books at the same time at most so they are counting on the confusion to sell a few thousand copies of the also-rans at the same time.

And these are only the ones I've seen in the past couple of weeks; I spotted four of them at Target just this afternoon, in fact - and Target has a very limited number of books on their store shelves. The problem is that I find the plot lines generally appealing but  only have time to work one or two of them into my reading schedule. How do I choose? Any recommendations? 

(The only one of these I've already read and reviewed is The Lost Girls of Paris and I found that one somewhat disappointing.)
