So there's this new website that looks totally awesome. It's called Emblazon, and it celebrates tween literature. Tween literature falls between middle grade and young adult on scale of target audience. Basically, these are your 6th-8th graders.
This website features current freebies from Emblazon authors, suggestions on books your tween might like ("If you enjoy Harry Potter, you might enjoy ____" type of suggestions), and all sorts of other awesomeness! This website is one you want to keep your eye on. Right now they're doing a rafflecopter giveaway for all sorts of awesome free books!
