Twelve-year-old Amber has the ordinary problems of a seventh grader: strained friendships, an annoying younger brother and, ugh, why can't her unconventional mother just act normal for once? When her wish comes true, Amber suspects it's not just her mother's behavior that's changed, but her actual mother! So where did her real mother go? Amber puts her best investigative efforts to work and discovers that one of her mother's silly claims-that they can view a parallel world in the window of an old industrial building-might not be so silly after all. Amber reminds us that everyone, including mathematically-challenged tweens with friend and family issues, has within them the power to effect change.
