I really like Green, and I adore everything that's ever come from Levithan's pen. I was excited to pick this collaboration up, and only a little nervous about it. I shouldn't have worried. The things that make each of these authors enjoyable are on display in this book, and their styles dovetail remarkably well. Green's usually a little darker than Levithan, so it was interesting to me that Levithan wrote the depressed will grayson. The characters are compelling, the storyline improbable but fun, and the writing is solid.
