I only have one book that I have a duplicate copy of and that is Fangirl by Rainbow Rowell! After I read it on my kindle, I fell in love with it~ You can check out my review here! When I saw it was on BookOutlet, I knew I had to grab a copy for myself. Then I saw someone haul the Limited Collector's Edition and I couldn't resist. It's seriously so pretty! Ripple was nice enough to model both books for me ;)
They're also coming out with Special Editions this year for Amazon, B&N and Indigo. I hope I can resist the temptation to get them all!
