Gary Russell has written a number of Doctor Who novels over the years, often tieing the plot heavily into continuity. With this Torchwood novel he does the same, bringing in references to the TV series and even Doctor Who (Boom Town). Unfortunately these references could be the undoing of the book in future years as the TV series ends up taking the characters in this story in a different direction.
In particular the use of Bilis Manger here as a character of ambiguous morality, rather than the obvious villain of the episode. If the TV series ever brings back the character (and I hope they do), will it take into account the events recorded here or ignore them and thus negate this story from continuity.
Aside from that, however, this is a darn good read with an intriguing premise: a block of houses that Jack can't go near. The overall plot focusses on Jack, but Ianto gets a fair whack in the story for once, which is good. It also presents an intriguing future that would not come to pass (because it involves Owen & Tosh).
There is also the implications of a sequel, which I hope we will get in the not too distant future.
