What it's about: When Emery was 6 years old, an alien spacecraft crash-landed in her small town. Whether they came in peace or with more sinister intentions didn't matter: a fierce battle erupted as humans fought for control over their new rivals, an alien species called the Atrians. In the midst of the conflict, Roman, a 6-year-old Atrian boy, found his way to a shed behind Emery's house, where she temporarily protected him from harm, bringing him food, comfort - and friendship. Ten years later, the Atrians have been acclimated to life on Earth, but they are interned in a heavily-guarded camp known as the Sector to keep them separate from humans. Now, for the first time, a group of Atrian teens will enroll in a suburban human high school, with the goal of testing the feasibility of human/alien integration. Emery and Roman find each other again in a school and a society that distrusts everything about the Atrians. While the world around them rages with anger and prejudice, their bond becomes increasingly strong and increasingly dangerous.
