Schooled by Gordon Korman

Such a sweet book!  Capricorn, or "Cap" for short, has been raised and home-schooled by his grandmother on a commune...by themselves, since everyone else has left the '60s behind.  When his grandmother has an accident, however, he's forced to live with a foster family and attend the public high school.  He starts off as the butt of all jokes and ends up a hero, learning (and teaching) many lessons along the way.  It's not a particularly deep book, but it's missing all disturbing elements that sometimes appear in YA literature, and it's a really nice story.  It would be great for Reading Bowl or Read Aloud
