Skyjacked

Six friends who attend Manhattan's elite Hartwell Academy are returning from an end-of-summer camping trip together on a private plane. Everything seems normal... except one of the regular pilots is sick, so there's a replacement; Cassie is starting to get violently ill for no clear reason; and they realize the plane is flying west, not east. Soon it's clear: the plane has been hijacked. But by who, and why? Where are they going? What made Cassie so sick? And even if they somehow make it into the cockpit and overpower the hijacker, could they land the plane? Emotions are running high, and choosing who to trust is a matter of life or death.
