A biological bomb has just been discovered in the air ducts of a busy suburban mall. At first nobody knows if it's even life threatening, but then the entire complex is quarantined, people start getting sick, supplies start running low, and there's no way out. Among the hundreds of trapped shoppers are four teens.

These four different narrators, each with their own stories, must cope in unique, surprising styles, changing in ways they wouldn't have predicted, trying to find solace, safety, and escape at a time when the adults are behaving badly.

This is a gripping look at people and how they can--and must--change under the most dire of circumstances.

And not always for the better.
