I've known about this website for years, and until now, have kept it my personal secret. I showed it to my agent who freaked over its awesomeness. It's simple, yet rocks. You always hear on twitter/blogs about new YA releases, but have you ever wondered where you could find a list of all the new releases at once? Well, wonder no more! Basically, it shows the latest young adult books to hit the market and links that show where to buy them.
Now don't say I never did nuthin' for ya. :D
