Do the Creepy Thing by Graham Joyce
This is an excellent story, which defied my initial expectations in an interesting way. It felt very realistic and grounded to me, despite having definite supernatural content. Both the setting and characters felt authentic, like these were things happening to normal people, not characters from a book. This might be because it's a UK book, whereas quite a lot of the YA I read is set in the US, although I think it says more about the authors grasp on his characters and honesty about their lives. There were a few elements in the book that could be described as 'issues', especially involving Caz's mum and her friend Lucy, but they weren't written like that at all. They were dealt with in a present-but-mostly-unmentioned kind of way, which is realistic even if it's not ideal. I thought that part of the ending was a bit too neat, but was happy to be surprised by the direction the story went.
