I've been teaching ESL for a while and I've been bogged down by 'why' questions. This book is the answer and I wish I had bought it sooner. It's not written like a novel, but it's very easy to look up stuff and hit the nail on the head. I won't be letting go of it now that I have my own.
It was probably just bad luck but the first topic I tried to get information about was gerunds and both the index and table of contents indicated a 7-page section of discussion but in fact there was nothing about gerunds on those pages. OF course, this means that other page numbers must be off as the pages were not blank or non-existent; just full of different material. This is a very popular book and is pricey (as a consequence?) but I am disappointed.
It is an excellent reference book, for both native speakers and non-native speakers...even better if you pair it with "A Practical English Grammar" by the same author. It is one of those books that you buy probably once in your live and keep it in your personal library as a reference over the years.
