Mmm... Maybe I'd choose The Mortal Instrument's world, 'cause it always fascinated me, but I can't say I wouldn't love to be part of the Dauntless faction :DDDD

The Hunger Games.
Yes, I liked Twilight but THG stole my heart (and broke it with Mockingjay) <3

Oh, God... This is a difficult one... I'm in love with every YA genre, but being reading The Immortal Rules (and loving it) I think I'll go with paranormal! :D

I'm finishing Shadow Kiss, by Richelle Mead, and so far it's amazing! Ca't wait to read the next installment :D
Would I recommend it? Hell, yes!
