A race against the clock in a nightmare world... Since the Outbreak, seventeen-year-old Kip Garrity is faced with a dreadful existence. Instead of studying for exams and going on dates like a normal teenager, he has become a prisoner in his own heavily fortified house - safe from the creatures that lurk outside but faced with a bleak and lonely future. His only companion is his father, a former Green Beret on a mission to teach Kip everything he knows about survival for when the inevitable day comes that they must leave home. But when Kip discovers his father is dying of sepsis due to a hidden wound, he must face his greatest fears and venture outside in search of medicine at the old pharmacy downtown. It's either that, or watch his only family perish. The only problem is, going outside might as well be suicide. His father will be dead in three days. Kip can make the journey in two, but he can't possibly plan for the horrors he will find outside his house...or a fateful encounter with another survivor that will pit him against his worst enemies in a race against the clock.
