What is a good title to name my teen book?

What's the book about?
Leave it untitled for now, until you write more of the book.
What I like to do is name the book after something a character said.
Something that involves the main theme and makes people think.
Like in a short story I wrote for my school magazine I titled it 'Maybe A Song'.
One of the characters in it is a songwriter and gives this girl advice on life. And he says, 'Come back next week and maybe there'll be a song.' and she says,
'Maybe a song?' And he says,
'Maybe.'

It's pretty simple I know. But you get the point? Answer this:

What is the point of this book? (Love story, getting over a death, finding out about life, getting over a fear, just having fun without a care in the world, etc.)
