Books like Words on Bathroom Walls

Adam is a pretty regular teen, except he's navigating high school life while living with paranoid schizophrenia. His hallucinations include a cast of characters that range from the good (beautiful Rebecca) to the bad (angry Mob Boss) to the just plain weird (polite naked guy). An experimental drug promises to help him hide his illness from the world. When Adam meets Maya, a fiercely intelligent girl, he desperately wants to be the normal, great guy that she thinks he is. But as the miracle drug begins to fail, how long can he keep this secret from the girl of his dreams?
