Users join a group of 6 and rotate books each month...so you contribute your own book and read 5 others that are sent to you each month. It's pretty cool...and it's free. So far I've read some great books.
Our book club tends to be a social gathering as much as a discussion group. Usually each meeting entails wine, food and, of course, the book. So we coordinate our reading, our food, wine all through Qlubb. It's just an easy way to manage each meeting and attendance. It's super easy and free.
Here's their blurb from the home page:
Have you ever wanted a better way to:
* see what your friends are reading?
* keep track of what you've read and what you'd like to read?
* get great book recommendations from people you know?
It's not just a place to list the books you read, but a way of comnparing books with friends, finding new titles, and just general social networking through books. I haven't used it a lot yet, but I like the idea!
