A friend who reads widely, and blogs on book topics, recommended LibraryThing to me about a year ago. LibraryThing allows you to catalog your book collection, meet friends via their book collections, and most important -- receive advance review copies of new books in exchange for reviews, or simply receive free books in exchange for reviews.
I'm running a Member Giveaway for Legs right now -- 100 free review copies released via Kindle. 61 LibraryThing members have signed up to get their free copies. All I ask is that recipients write a review on LibraryThing, Amazon, Nook, GoodReads, on their blogs -- wherever.
Join LibraryThing now and, if you're a steamy romance fan, consider requesting (and reviewing!) Legs. Giveaway ends July 19!
