Humans Versus Zombies

Students on summer break are exposed to a deadly virus, a neuroinvasive organism that is spread rapidly through direct human contact. The Infected are enslaved by the invading "swarm" intelligence and driven by an insatiable appetite to consume human flesh. Returning home, the students spread the infection to their fellow classmates and other unsuspecting townspeople. One by one, more students fall victim to the plague, triggering an epidemic that spawns a horde of ravenous zombies. (amazon.co.uk)
