Sydney Shieh is pitching at top form for the Central High Seabirds, but isn’t good enough. No matter how hard Sydney works, Rebecca Howard, star pitcher for the Seacrest High Jaguars, does better and looks effortless in the process. Sydney swears to take Rebecca down or learn her secrets.

Rebecca plays softball for fun, not competition. She doesn't believe in obsessive practice or softball camps or worrying too much about what other people think of her. But she keeps rising to Sydney's challenges.

Rebecca and Sydney can't leave each other alone, and their friends keep asking when they're going to admit what they really want. Even if their friends are right, how can they be together when they're out to defeat each other every step of the way?
