Shy twelve-year-old Pixie is the opposite of her gregarious parents, owners of the top party planning company in town. When Pixie's mum has to go away to support her ailing grandmother, it falls on Pixie to help out with the family business and step into the spotlight and mermaid costume - her worst nightmare. Along the way she learns important life lessons, like maybe her family isn't so bad after all and that stepping out of her comfort zone might not be as scary as she thought. With a little help from her friends, she discovers her courage and faces her fears.

Dogs are disappearing in her neighborhood, and Maggie Brooklyn Sinclair knows all about it. After all, she has a semi-secret after-school gig as a professional (okay, amateur) dog walker. Maggie may have a lot of leads, but she never suspected her crush Milo could be involved. . . . Margolis's fans are flocking to this stylish tween series featuring a clever and lovable new heroine.
