The author of the best-selling Emily Windsnap series spins a gripping tale about a girl who stumbles into the future--and must change its course to save a friendship.

Jenni Green's family vacation has finally arrived! Even though she has to deal with her annoying little brother, her slightly overbearing dad, and her very pregnant mom, she gets to spend a week with her bestest friend in the world, Autumn. 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.
