I have a specific book I've been meaning to read for awhile. I've heard that while it's a great journey, it's a dense / heavy / slow read along the way. It sounds like it'd be fun to read it together with a group of likewise interested folks.

Is there a service for pulling together reading groups around specific books, rather than the more common way of gathering a group of people and then selecting books? I'm imagining a website that has a sign-up page for ~every book and when ~10 people sign up for a book they all get an email introducing them to each other. Like if there was a bus stop for every book & when enough people had gathered, a bus appears & they depart together.

Given list of all the books, this seems like a pretty easy thing to make. Does it exist yet?
