Deadline by Chris Crutcher

How can a pint-sized, smart-ass eighteen-year-old make his mark on the world from Nowheresville, Idaho - especially when he only has one year left to do it? When Ben Wolf learns his senior year of high school will be his last year, period, he is determined to go out in a blaze of glory. That means not letting anyone know about his diagnosis. It means trying out for the football team. It means giving his close-minded civics teacher a daily migraine. It means going for the amazingly perfect, fascinating Dallas Suzuki. But living with a secret isn't easy.
