Query: Not really worth it.

I got this book and was disappointed. The book basically covers things you already know or at least things that you should know when it comes to dating in a long distance relationship. It's nothing new. It's the same old advice you've been given a million times. There's a few little interesting pages about long distance relationships in history, but really it's not that fun of a read. Highly disappointed.
