I wasn't kidding when I said that reading Will Grayson, Will Grayson made me put a bunch of David Levithan's books on hold at the library. I respectfully submit this afternoon's library haul as evidence:
Pictured:
21 Proms by many authors, including David Levithan (and John Green)
How They Met: And Other Stories
Wide Awake
Love is the Higher Law
Nick & Norah's Infinite Playlist by David Levithan and Rachel Cohn
(I've already read Boy Meets Boy.)
