Well, if I'm going to read more of the 8th Doctor novels at all, I'm going to have to start doing it in sequential order. Dipping into the series - in this case because I was interested to see a different treatment of the Princes in the Tower than we got in The Kingmaker - tends to confront me with characters (in this case Miranda and Sabbath) who clearly have deep significance for the author and for followers of the series but who are unknown to me. There are some vivid bits of description, and a twist at the end which I would have appreciated more if the whole book had not felt rather like fan-fiction in a canon I don't know much about.
(I note by the way that I've read about the same number of Eighth Doctor Adventures as [Seventh Doctor] Missing Adventures, but in general find the latter more approachable as a series. Is this a widely shared view?]
