3.5 stars, really. It was an interesting set up for a romance novel...childhood friends, high school sweethearts, separated by the war for three years, sure, but he came back home to the Ozarks and she was in California. Fully half the book had them separated and thinking back on their times together and rereading war letters. Then there was a mystery that each was trying to solve. There wasn't actually much time for romance, honestly. They ran parallel to each other more than coming together. I liked it (for some parts, I couldn't put it down), and I loved finding a world war II romance, but it wasn't quite it for me.
