At the Manhattan School of Art and Music, where everyone is unique and everyone is 'different', Gretchen Yee feels ordinary. It doesn't help that she's known as the girl who sits alone at lunch, drawing pictures of her favourite superhero, just so she won't have to talk to anyone. Her best (and only real) friend is there for her, but that's only if she's not busy - she's always busy!

It's no surprise that Gretchen isn't exactly successful in the boy department. Her ex-boyfriend is a cold-fish-sometimes-flirty ex who she can't stop bumping into. Plus, she has a massive crush on a boy named, Titus but is too scared to make the first move. One minute he seems like a sensitive guy, the next, he's a completely different person when he's with his friends. She can't seem to figure boys out!

Gretchen has one wish: to be a fly on the wall in the boy's locker room. What are boys really like? What do they talk about?
