I'm hunting around desperately for the last book of Gravitation so I can start a new series (probably going to be Tsubasa, because I want to see if Fai and Kurograne are as couplely there as well).
I think my favourite at the moment is -FAKE-. Takes a while to get used to the drawing style, but once you're there it's 100% worth it for the plot.
I haven't read that many though because they're so damn expensive. =___= I borrowed Furuba off my friend (what she had of it anyway), which was good. I only have FAKE, Gravitation and Eerie Queerie (which I want to get rid of because it's awful).
