Long Distance Advice

I'm sure a lot of us on here have been through long distance relationships... my SO left today for 6 months of training. When he gets back we will be moving to a new state and he will then again be leaving for a deployment of 6 months on top of that. This next year will be pretty lonely and will take a lot of self motivation and courage.. I am asking if anybody knows of good books for long distance relationships? Like actually read something that worked and helped them get through something similar? I have been looking to buy something but am at loss of what to get. I don't just want to buy the first thing I found on the subject, but want something more personable.
