In the scant few weeks since an explosion decimated New York City, sixteen-year-old Jesse has lived through the unimaginable. Only two types of people are left: Chasers, infected with a virus that turns them into bloodthirsty killing machines. . .and those they hunt. Jesse isn't waiting to be a victim. There's a collective of survivors in the city. Once he's located them, they can find some way out of Manhattan and Jesse can get help for those he's guiltily leaving behind.
