If you love your books, you might enjoy Good Reads as a way of keeping a record of your reading, checking out reviews of potential reads, and getting your hands on free books. They have a selection of giveaways that you can register an interest in. I put myself down for a book I hadn't heard of, by an author I didn't know - One Moonlit Night by Caradog Prichard (in English translation from Welsh), and it was one of the most enchanting and moving books I have ever read - and I would never have found it but for this site!
