Break the Ice -- and My Life

Ally and Lilly disappeared from McDuck Manor the same night Della did. When June breaks the ice the four- and one-year-olds are frozen in nearly 13 years later, they find their lives broken and their family over a decade older. Ally's little brother and sister, Hattie and Elliot, are 15. The unborn brothers and sister are nearly 13.
