When her parents died in a global pandemic, seventeen-year-old Cassie Thompson thought her biggest problem was finding her next meal. But “Telo” is a virally-transmitted genetic disease that targets adults, and no one is immune. Surviving to adulthood isn’t looking very good as her city succumbs to food shortages, sanitation problems, and gang violence. When Cassie accepts an invitation to join a group of young people living in a luxury hotel, she thinks her most immediate troubles are over. Her new tribe appears committed to alliance-building, order, and civility. She soon finds, however, that her new friends have very dark secrets and the boy she is falling in love with might be the most dangerous of them all.
