Back in the days of the Harry Potter book club, it was indeed pretty much as you say - one thread for every few chapters, then some separate threads for more general discussion of the characters, themes, larger plotlines.
At the time we tried to announce it a few weeks beforehand so as to give people time to get hold of the book, finish other books they're reading, etc. I guess in this case maybe better that you just start and others can join in later. Just let me know when you need me to Announce the thread.
Thanks- will do. I'll read the first section and then start it up. It may be this weekend before I've got time to read that much so will start discussing then.
Hopefully that will give pseudodragon time to get a copy
