October Books 1) The Twilight Streets, by Gary Russell
Really a rather good Torchwood novel, taking Bilis Manger from the end of the first season and Idris from the Who episode Boom Town, and also an alternate timeline which foreshadows a lot of future developments (blowing up the Hub, leaving Gwen, Rhys and their baby as the sole survivors of Torchwood). To a large extent it's a sequel to the episode End of Days, but much better. Lots of good character moments and exploration of what it means to be inside their skins. I must say that the Torchwood novels are proving generally rather a cut above the usual Who range; it's a shame that tie-in works get so little critical attention.
