I think I enjoyed the beginning of this much more than I enjoyed the end.
It is no secret that I love John Green. And, while I've never read any of his solo novels, I do enjoy David Levithan's writing. So it saddens me to say that I didn't love this book. The writing wasn't an issue. The two narrative voices were so different, it was easy to slip inside each of their heads. Will #1's parts had all the humor and complexity typical of a John Green, and the contrast between him and Will #2 was so in-your-face, it felt like you were getting slapped.

But for how good the writing was, I felt the plot to be a little lacking. I mean, the buildup was great. Especially with Will #1's opening anecdote about how you can't choose your friends. And then you had Will #2, who was sad, depressed and very clearly in need of a friend, and you couldn't help but think, "okay, this is going to be about friendship. I dig."

But the story sort of flat-lined towards the middle - with the whole Tiny and will #2 dynamic. It was so obvious where things were headed, I felt a little.. cheated. Was this... all I was getting? This? A break-up that leads to some sort of personality altering epiphany for the people involved? Say it ain't so.

The story ended up the way I predicted it would, except that it became all about Tiny. Which makes me feel like the story I just read was about Tiny Cooper, just through the Will Graysons eyes.

I know this book could have been so much better, but despite the disappointment, I did enjoy reading it, which is why it gets three stars.
