Joanie's got all of the problems of an almost seventeen-year-old girl. She's trying to get her driver's license, her mom and dad are pressuring her about going to prom, and she never can seem to make it to the bus on time. Even worse, Joanie likes girls, not boys, and all of the girls in her hometown are pretty darned straight. Her best friend, Zane, can attest to that – he never has trouble getting a girl, even if he's not interested in the freshmen who swarm around him.
When new-girl Kate shows up at school needing tutoring in math and chemistry, Joanie figures Zane will get the date, like he always does, and that makes life even more difficult. Joanie's in for a surprise, though, because Kate doesn't fall for her good-looking best friend. In fact, Kate seems to like girls, too, and things get a little scary when Kate asks Joanie out on a date.
Somehow, Joanie knows if she says yes to Kate, things will change forever. Can she manage to pass her driving test, get to prom, and come out to her parents the way Kate wants her to? Or will Joanie's seventeenth birthday be the worst day in history?
