Chess, the narrator, is sick, but with what exactly, she isn’t sure. And to make matters worse, she must share a hospital room with Shannon, her polar opposite. Where Chess is polite, Shannon is rude. Where Chess tolerates pain silently, Shannon screams bloody murder. Where Chess seems to be getting slowly better, Shannon seems to be getting worse. How these teenagers become friends, helping each other come to terms with their illness, makes for a dramatic and deeply moving read.
