I haven't been doing a great job of finding contests lately, but here's what I have found for the month of November:
YABC: You could win a copy of Alisa Valdes-Rodriguez's awesome book, Haters! Contest details here & see my review here.
As always, TeensReadToo.com has a monthly contest going on! This month, they're giving away copies of Kitty Goes Californian, Dear Zoe, Before I Go, and Fangs4Freaks. Also on the page are details about an essay contest and a contest to win jewelery. Details here.
On Bookburger, you could win a copy of Nicholas Sparks' latest. That's not YA, but they do have pretty regular contests on there. All you have to do is sign up for the b-list (their newsletter)!
So, you probably know I really like the Internet Book Database. You may not, however, have known that they give away free books every month! It's true. All you have to do is sign up and make sure your full mailing address is entered in your profile, and you're eligible to win!
Ally Carter (whose first book is on my to read stack) has revealed the title of book number two! Sort of. It's in code, and there are prizes for those who can crack it! Read all about it on Ally's blog, here.
Flamingnet has book giveaways for members every month. Sign up here!
