"A smart and wonderfully throwback adventure. Philip Pullman fans take notice. Don't miss."
—Matthew Quick, New York Times Bestselling author of The Silver Linings Playbook and Forgive Me, Leonard Peacock.

Nowhere to escape but below.

Panic grips sixteen-year-old Mia Kish’s boarding school, Westbrook Academy, when a mysterious quarantine is suddenly enforced by a small army of soldiers who shoot first and ask questions later. The quarantine makes no sense—but then students and faculty inexplicably begin to break down. Their illness is an aggressive virus that ages its victims years in only a matter of hours. The end result? Death.

No one can explain what’s going or has any idea what to do. Except Mia.

Because she knows something that no one else does. And she knows the only place to escape to get answers...But what she finds may be even more horrific than anything that came before.
