Colonel Dean Sturgis after his wife was killed has been living in the desert as a hermit. One day he goes into Crasburn, Texas which on the Mexican border. Suddenly the town is attacked by the forces of New Aztlan. Sturgis comes out of his self pity and inspires the residents to fight back against the invaders. It also reawakens his patriotism so he goes back to Hardbase Alpha. Well naturally they reinstate him back in command of the C.A.D.S. unit. He also convinces the President of the new threat. So he gets to take his unit down to Guatemala and recon the situation.
First they decide to help out a patron who runs a plantation against some giant mutant preying mantis. While Sturgis and some of this men battle the creatures the patron decides to betray those left behind and capture them while they are out of their suits. Fortunately Sturgis manages to defeat the mutant mantis with atomic hand grenades. Then come back and rescue his men. They continue on to the Golden Citadel of the Great and Powerful Moctezuma.(He’s never just the plain Moctezuma.) After a big fight against his high tech hordes of Aztec warriors they manage to destroy his citadel. Only the Great and Powerful Moctezuma manages to escape in his private jet pod.
Well this was a bit different from the past books. David Alexander decided to take a break from fighting the evil Soviet invaders for the evil Aztec invaders. Those damn Aztecs. Always causing trouble with their human sacrificing and hording gold. So apparently the dictator of Guatemala decided after the war to be the reincarnation of the Great and Powerful Moctezuma. With his stockpile of gold from drug dealing he manages to acquire vast reserves of high tech weapons. His ultimate goal of course is world conquest. We get a nod to Syvertson in the obligatory scene of the C.A.D.S. letting down their guard with a supposed friend and getting captured out of their suits. Otherwise the book was just one big exercise in constant fights with high tech gadgets. We get all sorts of helicopters and missiles and rocket bullets for AK-47s. Oh and the C.A.D.S. now have nuclear hand grenades. Wow what I great idea. Wonder why nobody ever thought of that brilliant idea before. Surprisingly they manage to work well for the C.A.D.S. So once again the world is safe from the evil Aztecs although the glaring grammatical errors still continue.
