I didn't know the first thing about this book, until I reluctantly read the back flap (I like to go in blind, not knowing what to expect) but am intrigued as I approach it, mainly in it being a collaboration with another author and also as a fantasy adventure story. As long as it's better than The Gunslinger, that is.
I'm also interested to see how the collaboration thing works. I don't think I've ever read a co-authored fiction book before. I was going to ask the following questions:
Will the distinct voices come through? Do I know King's style well enough to know when it isn't him writing? How did the writing process work? Did they go off and write sections separately and then edit together etc. and then went googling and found the following interview with Peter Straub - http://www.liljas-library.com/showinterview.php?id=8 where he talks about it and answers all of those questions. Nice.
I've never read anything by Straub before either. If any one has any recommendations, you can leave a comment below or you can find me on Twitter - @Mattowar. I'm due for an audiobook mission after a few months' break.
