A little bird tells me that Neil Gaiman's newest, The Graveyard Book, is being offered with your choice of illustrators in the UK. Dave McKean, who illustrated Coraline to deliciously creepifying effect, has the "adult" version and Chris Riddell the kids'. A quick Amazon check tells me that the US seems to be sticking to McKean for both.
I got a cover image (over to your right) of Riddell's work, enough to see that although it's not the angular creepiness of Dave McKean, it's not fluffy bunnies.
I read an ARC without any illustrations (sigh), but it was a great yarn nonetheless. Has anybody seen either or both of the versions? Can you weigh in?
ETA: Betsy Bird over at Fuse #8 has a much more thorough gathering of the various covers. Take a look!
