A bio-engineered dog battles for its life and the right to live. The author of CHILDREN OF TIME, winner of the Arthur C. Clark Award. Rex is my name. I'm a nice dog. Rex is also seven feet tall at the shoulder, bulletproof, armed to the teeth with heavy calibre weaponry, and his voice resonates with subsonics specifically designed to instil fear. He's part of a Multiform Assault Pack, along with Dragon, Honey, and Bees, operating in the lawless anarchy of Campeche, Mexico. He's a deadly weapon in a dirty war as a genetically engineered Bioform. He only wants to be a good dog. And in order to do so, he must do exactly what Master says, which includes killing a large number of enemies.
