The world without a future

Nurrin has lived her entire life with zombies--trapped behind walls meant to keep them safe. She's mostly happy there but when a zombie horde breaches the walls of her Haven, she has to trust her brother, Collin, and his best friend to keep her alive. Finn O'Malley has given up voicing warnings that are ignored. No one cares that the zombies are changing. Now all that matters is keeping Collin and Nurrin safe from what is outside the walls of a Haven. But when Nurrin's best friend picks up a contact infection, he agrees to get the medicine needed to save his life. Forced together, relying on each other in a strange Haven, zombies aren't the most dangerous thing they are facing.
