Devolution — Juliet Cardin

Ayres and Amanda have returned to Planet Taleon to exact revenge on Calixtus. Tired of running for their lives, the pair is joined by an outcast scientist and together they devise a way to rid themselves of their nemesis -- for good. Though their plan goes slightly awry, the outcome they desire is soon achieved, but with devastating, unforeseen consequences. Now they must return to Earth and fight for mankind's very existence, before another game takes place -- one more terrifying and brutal than the one played on Taleon. A game that will end humans, all for the sake of an alien world's grisly entertainment.
