Coraline by Neil Gaiman
This book is about a girl called Coraline who has moved house. Unusually, there is a strange door leading to a parallel universe and a parallel mum and dad with white papery skin and black button eyes which looked like they could go on for forever. What will she choose to do? This is a total adventure book but do not read if you get scared easily.
WARNING: Do NOT read under the covers at midnight!
