This was my first David Mitchell experience and will certainly not be my last (especially after reading up on this when I was finished and finding out his books all have little connections since they take place in the same world...so cool!). This was adequately creepy and beautifully written - the best kind of ghost/horror story. All of the characters were well done - particularly our dear friends Norah and Jonah - and while I hadn't read The Bone Clocks (there are apparently a lot of crossovers with it) I appreciated this as a standalone novel. If all of Mitchell's stuff is as well done as this, I have a lot of fun reads in store for me! 
 Side note: the audio was awesome. After much trial and error the past few years, I think I'm officially an audiobook convert!
