CogLing is a vast fascinating world that cannot be jammed into a few chapters. But this one is good enough as an introductory book. I'll be needing to scan & skim some of the chapters again.
More or less skipped the last 2 chapters or so. All in all it's a very interesting read, especially for people who are interested in (cognitive) linguistics, since it offers some basics and has a lot of exercises to help put theory into practice
