Do you have just a single book you'd like to talk about? This is the place to do. Create a topic about your book and see if anyone else will join with you to talk about any burning ideas, predictions, themes, characters, etc.
If you think you have a point that it a bit spoilerific you can use a spoiler tab, which is really easy to do. Just type in < spoiler > your thoughts < /spoiler > In order for it to work though, you would need to remove the spaces after < and before >. Example: (view spoiler)[ cool, isn't it? Use it so people don't get spoiled on key moments in your discussions. (hide spoiler)]
