But twelve-year-old Jenni's world turns upside down when she takes an old elevator to visit Autumn and discovers that everything has changed: not only is her friend in a different condo, but tragedy has struck Autumn's family, Jenni's mother has had her baby, and everyone is a year older. When Jenni realizes that the elevator caused her to skip a whole year, she tries to go back, but soon finds that fixing things won't be as easy as pressing a button. How can she alter the past and keep her family and Autumn's from falling apart? With honesty and insight, Liz Kessler explores how the bonds of family and friendship can endure through time.
