If You Love Me — Barbara Steiner

Argie has never loved anything the way she loves tennis. But when she meets fellow player Chris, she knows that's about to change. He's everything she could want in a boy: friendly, cute - and he enjoys tennis, too.

But then Chris starts breaking dates with her, forgetting to call her - he even leaves in the middle of an important tennis match! What's worse, Chris won't tell her what's wrong. Argie knows that she's got to try and help Chris. But she also knows that if she discovers Chris's secret, it could break her heart.
