A splendidly creepy story of the Doctor, Amy and Rory (set between the wedding and the opening of Season 6) at a Swiss sanatorium in the late 18th century where almost nothing is as it seems. James Goss varies from entertaining to excellent as a Who writer, and this is a particularly inventive novel, told from the points of view of various narrators, including the Doctor, Amy and Rory, all of whom turn out to be unreliable in one way or the other. As with any Who-related work by Goss, this is strongly recommended.

I started it by listening to the audio version read by Clare Corbett and then realised I had the paper copy of the book, so read the last two thirds in dead tree format, really because I am a quick reader and wanted to find out what happened; Corbett's reading, and in particular her characterisation of the different first-person narrators with their varying accents, is excellent.
