Game Hunter: Book One of the Game Hunter series

WHOSE SIDE ARE YOU ON?
An underground chemical explosion turned the City of London into a Devil's play-ground. With it was born the live TV death show between zombie and man called 'Game Hunter'.
Eighteen-year-old male and female, Tremayne and Red, are two of the seven dangerous zombies chosen to play a series of three games against seven of the best game hunters money can buy. As the first game gradually approaches, why are we rooting for the zombies?
THE FIRST OF FOUR BOOKS IN THIS HIGHLY ORIGINAL ZOMBIE SERIES.
