A very pleasant reading on the whole: the book is written in a clear style, has some very good ideas (the changes of the nature of freeholds along the different ages is clearly the best one, and sent my imagination flying) as well as some useful mechanics.
Two mains flaws lower the quality of the book, however. The first one is that it is perhaps too focused on mechanics and less on stories (contrary to Freeholds & Hidden Glens from first edition). The second one is, while it is a book heavily focused on mechanics, there is none on the transforming of glens into freeholds and no development on the reasons Kithain do this to the detriment of the Nunnehi (which would have warranted more explanations). Finally, the third flaw is the examples given of freeholds all over the world. While it is a very commending effort to enlarge the scope of changelings (and not focusing only on Concordia), the presence of only sidhe, trolls and other Western kiths in places like Africa grates on my nerves. It is something which I already noticed and regretted from the main C20 book, and the trend seems to continue.
Despite all these critics, I enjoyed reading the book, it was a very pleasant read, and, regarding the story-contents, I like reading the different examples of freeholds.
