Under the System everyone is assigned a numerical Score that decides their worth to society and whether they live or die. Charley has escaped from Meritropolis... but in his quest to take down the System that has taken his brother from him, he must go through Meritorium, a city where gladiatorial games of life or death combat are waged between High Scores and Low Scores, man and beast. Charley and Sandy must face man-eating plants, religious zealots, slave traders, and the ever present mutant animal combinations that roam a dystopian Coliseum presided over by Emperor Titus, the one man standing between Charley and the answers he seeks. Man is not an animal, but if they are to make it through Meritorium, will they even be able to tell the difference? The lines between man and beast, friend and foe, will blur in Meritorium, the riveting sequel to the bestselling Meritropolis.
