BBC Books 8th Doctor books have been mired recently in a muddled series of alternate universe stories, with a nebulous threat attempting to take over history hanging in the background for the last couple of years. The feeling of going nowhere seems to be lifting, as we finally get some answers to a number of unresolved plot-threads in Timeless (what Sabbaths plans are, who his employers are, the Doctors destruction of Gallifrey, resolving the paradox that led to the alternate universes co-exisitng, Anji's attempts to get home), and while not everything is resolved the series at least looks to be moving forward again instead of wandering in circles. Coupled with a decent tale of people jumping from alternate Earths's to the 'real' Earth, this is Stephen Cole's best book to date.
