Over on his journal, Neil Gaiman is discussing the fact that The Graveyard Book has made it to 52 weeks on the New York Times Children's Bestseller list. I got The Graveyard Book (audiobook) as my first download on my Audible.com membership and I'm loving it. I'm not to the end of it yet, so I suppose it's theoretically possible that it all goes to pot in the last chapter, but knowing Neil's previous work and suspecting how good a book would have to be to even get into the 10-place-long Children's bestseller list, I think that's highly unlikely.
This is an amazing achievement. Congratulations, Neil.
