Contender Trilogy

Cade Carter is lost. Convicted of a crime he didn't commit, Cade is facing a year in reform school when he finds himself suddenly transported to another realm. But this new world is no escape. Populated by bloodthirsty prehistoric creatures and fierce warriors, Cade's surroundings are full of danger. Along with his fellow students, Cade is forced to become a contender in a deadly game of the highest stakes, controlled by invisible overlords. Who are these brutal rulers, and why did they choose Cade?

In a world far from our own, where enemies come in many forms, the ultimate battle for survival continues.... Cade Carter has been chosen. In a realm of monsters and warriors, Cade is an unwilling contender in a deadly tournament controlled by the brutal alien overlord Abaddon. Cade may have won the first round but the fight isn't over yet. For his next battle he must duel a seven-foot-tall, clawed monster - the reigning champion of an alien race. Losing will lead to earth's destruction.

Cade has managed to survive the duel with the Hydra Alpha - barely. But the Games are far from over. By order of the cruel and mysterious alien overlord Abaddon, Cade and his friends are sent off to war against the Greys, a humanoid race that has far surpassed humans in technology on their home planet.
