I just finished re-reading Looking For Alaska by John Green. I still think it's my favourite. I just started re-reading An Abundance of Katherines by John Green.
I'm reading WILL GRAYSON, WILL GRAYSON atm, not blown away but it's still good. Not as good as LFA by John Green, though.
Also recently finished: TORN by Cat Clarke, DEADLY COOL, DRIVE BY, and I re-read THE SUMMER OF SKINNY-DIPPING.
