The actual ghost story part of this was brilliant - I had chills at the end, and desperately wanted to find out what was happening. However, I think this suffered from just being too short. While, obviously, being a world book day book meant that it couldn't really be any longer, I just felt like I was missing a lot of background information and depth on the characters and the setting. I felt that the characters were very interesting and complex but that that wasn't really explored, and to try and compensate then some portions of the book, especially at the beginning, lacked subtlety. I felt that every single point of the book should have been expanded on; it read a bit like an abridged version of a novel, which is a shame, as the actual plot and premise were great!
