September Books 17) Storm Harvest, by Robert Perry and Mike Tucker
A Seventh Doctor novel set between Survival and the start of the New Adventures, following sequentially from Matrix by the same authors. Having just listened to the Big Finish "Lost Stories" set in the same chronological gap, I am struck by how much better both this book and its predecessor are. From the story point of view, it is a basic alien invasion of a future human colony; but there is a lot of very pleasing homage to hard sf classics, particularly the intelligent dolphins of David Brin's Uplift series, and monsters reminiscent of the various works of Larry Niven. Ace, as sole companion, gets some very decent character development setting her up for the more mature arc of the New Adventures; Perry and Tucker remind us that she has already been travelling with the Doctor for three years by this point. So, rather a good one.
