I recently acquired a copy of the above book, but haven't had the time to start reading it properly. It does appear to be one of the better books on the issue, with a proper analysis of the monarchy's future. While it's written with a pro-monarchy slant, and in the context of Great Britain (it only mentions in passing that the Queen is also head of state of 16 other Commonwealth countries - that's how much we matter to the monarchy), the book looks closely at the questions arising from Prince Charles succession to the throne, and the future of the monarchy. It even takes a look at the "alternative to the monarchy", that is, a republic.

The significance of this cannot be overstated - most books on the monarchy or Royal family have one or two paragraphs on the "alternative", this book has a proper full-blown analysis. It says a lot that a pro-monarchy book would even bother taking the time to argue against republicanism. It used to be able to be dismissed by a few strokes of the pen, now it takes a chapter of keyboard strokes.
