Dying to know how Hunter knew the Beatles lyrics

It's amazing how much an author can cram into so few pages. It was interesting enough wondering why Hunter wouldn't talk to anyone until he saw Caroline but then the whole Beatles thing has really heightened my interest level. I'm also drawn to Caroline's relationship with a soldier as we share that in common. I'm excited to read this one as the author is someone I have wanted to read books by but just have never gotten around to it. And it has such a pretty cover.
