When Zoe enters the annual Perform-O-Rama organ competition, she finds that life is full of surprises—and that perfection may be even better when it's just a little off center. Ten-year-old Zoe Elias has perfect piano dreams. All she needs is a baby grand so she can start her lessons. But when her dad buys an organ instead of a piano, Zoe's dreams hit a sour note. And the organ isn't the only part of Zoe's life that's off-kilter, what with Mom constantly at work, Dad afraid to leave the house, and that odd boy, Wheeler Diggs, following her home from school every day.
