This is a good, basic, but now somewhat outdated introduction (copyright is 2012). Also, it's self-published, from what I can tell. We all know what that means.
That being said, it provides a good few ideas and tips on how the many ways to use mind maps and construct them.
Ultimately, when it comes to mind mapping, practice is everything, so, no book can really be substitute for that. But this also where the book is not quite successful and shows its "age": there are many more software available now to practice.
