Query: Pretty good basic information and encouraging

Pretty good basic information and encouraging. Though the author has gained her expertise from a very narrow set of experiences writing about her special topics, the info is still very good and there is surely learning there for everyone. Also gives you an idea of how much money one can get from writing and gives you several ideas and things to think about. If you are considering writing a book, this book is a good first step, before you expand too much effort. There are a few things you may do differently as a result. And the book is not only a fun light read, but also very detailed sort of like a handbook.
