This book had surprisingly sloppy handling of examples and underlining/italics. For example in ch. 7: the example says “I wish I could feel relaxed about [...]” whereas the text discussing the example claims in all three instances that it says “I wish I could feel more relaxed about [...]”. In the place, while discussing the subordinate clause “I could feel more relaxed” the book doesn’t underline the personal pronoun in its first mention, but includes it in the next two places. There are many other mistakes like this scattered though the book, which is doubly frustrating seeing as this is a book about grammar. There are also an astounding number of mistakes, so I’m almost tempted to congratulate them on getting them all through multiple editions. On a more positive note, the actual contents are informative, and the examples used do actually illustrate the points well.
