This is an incredibly bizarre book. As far as general introductions to Taiwan's history, I think that Denny Roy's book or the compilation book Taiwan: A New History, might be better choices. This book sort of summarizes the pro-independence stance in Taiwan on its history and thus attempts to write a case for a Taiwanese nationalist history. But it is written by an outsider, albeit one who is trained in and researched Taiwanese history before, but does not live in Taiwan. In that sense, it would probably be better to read some things by actual Taiwanese people on these matters. The book is also almost 20 years old now, and a lot has changed since then. So maybe it could be interesting to assign it to teach with alongside something from a more KMT stance? Not sure.
