Book Army is THE site for lovers of books. The easy to use site allows you to create lists of books you've read, you want to read, or you've blacklisted (never want to touch). It's goal is to make sure you "never read a bad book again."
If the suggestion services don't produce anything intriguing, you can browse books by the network's most read, most popular, and by author. Join book groups of similar interests, add friends and see what they're reading, etc.
