I can find it with a Portuguese IP on Amazon.com Just type Nancy Nap on Amazon.com's first page search box with "all". It shows right away.
The book brought nothing to me. I read what was on Amazon in a professional manner.
It needs lots of work. For flow, for ideas to be clear, for tipos, for editing. And you need to find someone who can do the proofreading that is not you or your editor. All those tasks are different and have to be done by a different person.
Formatting/lay-out/fonts/font sizes, etc. must also done by someone who knows how to do it.
You also need to explain who the Leaver is. Second paragraph of the first chapter has "The Leaver had an explanation...", but who is he and why do you call him that? And shouldn't it be "... that warm day in April would..."
There is nothing about MLC on the book description be it on Amazon or your blog - there is a mention inside the first chapter. Without it, is is just one more book about a guy who leaves and divorces.
You also need to think you are writing for a wider audience, not on your journal or on HS. It reads like HS posts or a journal (that needs a lot of editing) and a book has to be more than that.
There is too much swearing and name calling right from the start. Again, it reads like your HS's posts.
