A book by David Mitchell is nearly impossible to summarize; one, because they are complex and layered and two, because giving any description is possibly ruining your experience of reading it and making your own judgement. I will say for any fans of Mitchell's work, that this story contains an extra treat in the form of links to his other books. The Bone Clocks has elements of humanity, the paranormal, myth and future all wrapped up in the lives of interlinked characters and situations throughout. An exhilarating read!
