Tweed is the ultimate slacker. He has zilch in the way of plans. But he's about to learn how fast zero can go negative. High school's out, summer's afoot, and Tweed's content to do the usual...hang-out with friends, drink beer, get stoned, and steady bomb the neighborhood with graffiti. Yeah, he's got nothing much else in the works and that's just the way he likes it. That lasts about half a day. Soon enough Tweed is upside down and in over his head. He's falling for Chloe, his best friend's girl. Hot though she may be, that one has a few issues of her own. And then there's some gang-bangers out to thump his head. Not enough? Tweed's grandfather, the man who raised him, is getting harder and harder to keep nailed down. Until ol' Pops goes all broken arrow and off the reservation entirely, that is. Yup. Whether Tweed is ready for it or not, the time has come for a boy coming of age.
