This is actually a very useful book. Unfortunately, the pitching and marketing are completely wrong. Basically, it is an aid for teachers or for fluent English speakers to enable a non-native speaker to learn English. As such, it's invaluable, and should earn five stars.
However, it is being marketed at complete novices, and as such, it is written in far too complex terms and is nowhere near accessible enough to someone working on their own. In the right hands- eg a teacher, a relative, a fluent English speaker helping a friend to learn the language, it offers excellent advice ( by the way, much of which would be very useful to native English speakers- this would make an excellent classroom tool for any PGCE English student teacher).
But given to a non-native speaker without a strong basic grounding, it will be confusing, difficult and ultimately pointless.
Use it properly! There are many good things here...but it needs help.
How about a rename?
