What do you say to a beloved childhood friend whom you haven't seen for the better part of a century? And you haven't aged a day in all that time.
Emily Jane Adler and Jo Bowser, two girls growing up in 1920s Oklahoma, promise each other to stay young and together for the rest of their lives. Their plans, however, are upended when one bitter winter day, Jo mysteriously disappears, leaving Emily devastated and alone.
As Emily blossoms into a lovely fifteen-year-old, her determination to find Jo and the means to do so become her obsession. But fate is not quite through with her yet. Along the way, she encounters an inexplicable geological event that catapults her into a strange new world and ultimately into the arms of a young woman named Eleanora MacNab-a woman who has been anticipating Emily's arrival for the past seventy-five years.
