They escape together, hoping to find help in Boston with Dr. Agatha Varden, one of Old Harmonie''s pioneering founders.
But the outside world is nothing like they anticipated. As they face challenges they never expected and encounter a group of kids from the outside, Mori and the others begin to understand the complicated reality of their supposedly perfect community. With the help of these new friends, they just might be able to save Ilana . . . but at what cost?
