Bobby Phillips is an average fifteen-year-old-boy. He thinks he knows what it's like to be invisible; he's used to being ignored by the popular kids at school (especially the girls). Even his parents hardly seem to notice whether he's home or not. Until the morning he wakes up and can't see himself in the mirror. Not blind, not dreaming — Bobby is just plain invisible. There doesn't seem to be any rhyme or reason to Bobby's new condition; even his dad the physicist can't figure it out. For Bobby that means no school, no friends, no life. He's a missing person. Then he meets Alicia. She's blind, and Bobby can't resist talking to her, trusting her. But people are starting to wonder where Bobby is. Bobby knows that his invisibility could have dangerous consequences for his family and that time is running out. He can't stop wondering if he'll ever reappear, especially when his parents wreck their car and wind up in the hospital. Now Bobby is all alone. How can he survive in a world where he can't be seen? One thing's for sure: Bobby's not going to just wait around to see if his body will decide to show up again on its own. He's got to take action. Fast.
