Many readers really dislike this book. I was not quite that put off by it. The book is basically in three parts. Part 1 is the set up, where Doctor 5 and his first crew get caught up in a situation involving a planet being guarded by a space station on which no one in the crew really cares. Russell spends quite a bit of time getting into characters' heads, showing us what he thinks the TARDIS crew really think of each other, and most of it is not nice. The Celestial Toymaker is hanging about, but his exact relationship to what else is happening is somewhat elusive. At this point, the novel is fairly straightforward Doctor Who fair with a few of Russell's typical revisionist tendencies. Part 2 is a long flashback to the Doctor's time at the academy on Gallifrey, meant to explain how he became familiar with the Toymaker who shows up in The Celestial Toymaker first Doctor episode. The Gallifrey sequence is probably the weakest part of the novel, mostly because here Russell lets loose his penchant for feeding red meat to the fans. Thus, we find out that pretty much all of the various rogue Time Lords the Doctor later encounters - The Master, The Rani, The Meddling Monk, Drax, and so on - not only went to the same school (no surprise there as we have only ever heard of one academy on Gallifrey), but were all part of the same collection of misfits who hung out together and got into trouble together. They were all friends of some kind. This is really wholly unnecessary other than to save Russell the trouble of having to invent new characters. All of this slowly leads up to The Doctor's first encounter with The Toymaker. Part 3 returns the reader to the "present" and a showdown between The Doctor and The Toymaker. So, the novel is really dragged down by Russell's desire to throw into his story as many Doctor Who references as he can, not just to prior Doctor Who TV episodes, but also to prior Doctor Who novels and to his own Doctor Who novels and dramas. Had Russell bypassed all of that and stuck to the story, "Divided Loyalties" would have been a much better book than it is.
