I have an extra, new, unread copy of Catching Fire by Suzanne Collins (sequel to Hunger Games) and also of Shiver by Maggie Stiefvater. If anybody has some YA books they are trying to get rid of, I will willingly mail my two out to you in exchange for 2 I do not currently own. I also enjoy mystery and fantasy. Slightly used is okay.
I'd ideally only like to send out one package, but if you're only interested in one, go ahead and say and we'll see who's interested in what.
ETA: I turned up my extra copy of The Lightning Thief as well (it's the one with the lightning bolt on the front that doesn't match the rest of the series), so also if anybody's interested in trading for that.
I swear to god I am going to make a list to take with me to this damn thing next year. Or else get an iphone just so i can have that app that keeps track of what books you own.
