I've written a book set in Thailand. It's called Thailand Calling and it's about a Chicago columnist that has a midlife crisis and without any notice suddenly leaves his wife and job to chase prostitutes in Thailand. It might sound like a story you've already heard (or maybe even your own story) but it's got some twists and is very well written. The reviews so far are excellent. If you haven't checked it out already, you can find it on Amazon or any other book site. On Amazon it's also available in print. http://www.amzn.com/B00OYTJZM2
