Single. Inept at flirting. But at least she's got talent and a sense of humor. The problem is, she's often the punch line. Despite her difficulties, Ellen Blum is proud of the cred she has earned serenading brides down the aisle with her harp.

As she dodges the barbs and petty crimes of her bosses and copes with a family crisis, she feels more like a child than ever. She has her heart set on silencing her critics and teaching them - and maybe herself - a new tune. But becoming more than the person described on her business card is even trickier than moving her harp.
