Twelve-year-old Phoebe Callahan longs to enjoy a storybook Christmas. So after she learns that she and her three girl cousins will spend their holiday vacation in New England on their grandma's island estate, she plans the Christmas of her dreams.

But after Grandma Gee's heirloom angel shatters, Phoebe learns that life's greatest joy comes from giving to others.
