Bones of Betrayal

I have very little interest in fictional stories about nuclear war and less about WWII. The entire first third of the book was a history/science lesson and I almost DNF'd it but it's a series and I can't skip a book in a series! Besides that, the mystery wasn't that interesting and was all over the place. The romance was weird, his only interest in her was mostly her resemblance to Jess. If this had been the first book I don't think I would have kept reading.
