Love: little word, big consequences. Clarissa has never given much thought to the word herself; she has other things to worry about. Her mother is still recovering from breast cancer, and until Clarissa hears that magical word "remission," she doesn't think she'll ever be able to relax.

As a distraction, she and best friend Benji try out for a community production of The Wizard of Oz. But sadly only he makes the cut, leaving her disappointed and best-friendless, and forced to spend her time with other people, like boy-crazy Mattie.

When Mattie becomes distracted by a new crush, and Clarissa's mother starts spending far too much time with her personal trainer, Clarissa wonders when she stopped being enough for all the people in her life. Enter Michael, who seems to be interested in more than just friendship. But is that what Clarissa wants?
