The Palahniuk book is about 23 wannabe authors who get locked away to help them find their 'muse'. The longer they stay there, the more we find out about these authors and the stories they tell (the book is partly a story about the authors and partly the stories they tell as they go slowly insane). The book starts off with a bang, but struggles to maintain that level consistently throughout. Some of the author's stories were enjoyable/fun/interesting. The rest were less memorable if I'm honest.
I haven't sat down and read a book in a day for a while, but that happened with Laurell K. Hamilton's Guilty Pleasures. Personally, I've like the hero to have a 'smart mouth,' which is probably why I liked the lead character in this book (a female vampire slayer-cum-zombie maker), and authors like Janet Evanovich and Dennis Lehane. It's never going to be compared to Bleak House or Hamlet, despite that it's still a good read all the same.
The book is the first in a series using that character centrally, and I was wisely advised by someone at the bookstore that the author takes a sudden left turn about half way through the series and suddenly starts writing erotica about that character. I'm not sure why she does this and I don't think I'll go through that door with her, but I'll read all the books up to that point.
