Debbie Valero
Debbie Valero is one of the kids to whom Clio Mongley gives piano lessons. Perhaps the biggest challenge Clio has with respect to Debbie is to keep her from destroying the piano with her enthusiastic pounding; it's difficult to convince her to play any passage anything but fortissimo.
Debbie brings the same overwhelming enthusiasm to virtually everything she does, and while she's good-natured and cheerful she can be somewhat dangerous to be around. Her parents call her their little angel and seem oblivious to her destructive capabilities.
