The Ghosts of Heaven by Marcus Sedgwick.
Finally finished reading this book I had started in November. It took me so long because it is hardback and big – I much prefer paperback. The story is actually written as four different short stories all linked together with the common theme of spirals. maybe I would have been able to read it quicker if the four parts were separate rather than bound together as they are. Either way I am a huge fan of stories by Marcus Sedgwick and really really enjoyed this book. Perfect for those who have lost anyone they love as the message is to do with death.
