I bought this book after doing a brief review on-line and after reading the five-start comments and it turned out to be a big disappointment. It claims to be in plain English but, what it really is, is a very poorly organized book explaining grammar in a different vocabulary than what most of those who study languages know. Good luck finding rules, exceptions, etc. in this book. If you are a foreign student learning English, forget it, it will be completely useless to you. This is definetely going to be returned and replaced by a better book.
