November Books 1) The Ancestor Cell, by Peter Anghelides and Stephen Cole
This is the first of the books setting up the Faction Paradox timeline which I have enjoyed. The Doctor and Fitz return to Gallifrey in Compassion-as-Tardis, and find themselves implicated in a power struggle between President Romana and one of her predecessors, resurrected by the Faction Paradox. It contains the seeds of numerous ideas which we have seen in later stories, particularly the Gallifrey audios (though they of course feature Romanas I and II, whereas here it's clearly another Romana), and ends with the original Tardis regenerating itself and the Doctor stuck on Earth with amnesia - both picked up more recently in Big Finish continuity. Most importantly it rounds off a significant story arc, going back to the start of the BBC Eighth Doctor series in some ways, and does so very satisfactorily. Sometimes Who stories playing with Gallifreyanm drama and temporal paradoxes get too clever for their own good, but this is just about right. Very satisfying.
