NaNo book -- what to do

So November went pretty well with the completion of my second NaNoWriMo book. I was fairly excited to have created an entire novel. And I thought, apparently naively, that the summer would be a great time to take care of the revision.

Well, here's summer, and the revision is as follows...

Nothing at all.

I am trying to figure out what the basic message of the book is, and that seems to be the hardest part. So if I don't know what the point of the story is, how can I possibly make it better? Naturally, the first step would be to find the point of the story.

So I have this boy Simon who has an incident in his past that is hidden from the reader until about two-thirds through the book. The incident links with the disappearance of his best friend Troy. Now I know how those two things go together and I know how Simon is linked to them both, and I mostly know Simon's motive in each of them, but I'm not sure what that says about Simon. WHich means that overall I'm not sure what the point is. The point can't be that sometimes we're in bad situations and have to make the best of them by protecting ourselves. That's sad and lonely. I don't want a theme like that.

But Simon's point seems to be that he is sad and lonely. He wants so much for Callie to like him and he wants so much to be like Troy. So if his point is that he is sad and lonely, should he be the main character who "wins" in the end? I'm not sure.

Also, the title Cry Wolf doesn't work anymore. I have no idea what to call it now.
