This is the first time I've done one of these, so I'm very curious to see how it works out. I'll be doing for for Moving in early February. I'll report back how it goes.
If you're looking for some insight on how to run giveaways for your book, I highly recommend this post from Novel Publicity & Co. I think I'm also going to try using Rafflecopter for some giveaways that aren't Goodreads focused, and will try to spread the word a little more (thanks to my friend and fab YA author, Diana Renn, for showing me Rafflecopter).
