Reports show massive build-ups of mining drones infected iwth the alien transmode virus near all PTMC holdings outside the Sol system; estimates put total contamination at forty-eight hours.When intelligence reveals that an alien command post or ship is directing the mech invasion, Benjamin St. John is paired with a sexy, tough-as-titanium Collective Earth Defense pilot and ordered by PTMC Director Samuel Dravis to find and destroy the alien stronghold.But first Ben and his partner must battle thorugh an unprecendented attack by CED and PTMC mercenary forces and uncover the mystery behind it--all while contending with the blackmailing, double-crossing Director Dravis, who schemes to crush the mech invasion and his bitter enemy, the CED, in one fell swoop. But his plan has a flaw, for his instrument is again Ben St. John--ex-Marine Corps pilot and control freak hell bent on saving the universe, collecting his money, then kicking Dravis's butt from Sol to Tycho Brahe. less

With the galaxy exploding all around him and humanity itself in jeopardy, Pyro-jockey Ben St. John knows who the real enemy is -- his former employer, Samuel Dravis of the Post Terran Mining Corporation, the undisputed power behind the most awesome corporate entity in the solar system and beyond; the traitor who cost Ben his wife, his future, and reduced him to a galactic renegade with no allies except a handful of star-wanderers and misfits... moreWith the galaxy exploding all around him and humanity itself in jeopardy, Pyro-jockey Ben St. John knows who the real enemy is -- his former employer, Samuel Dravis of the Post Terran Mining Corporation, the undisputed power behind the most awesome corporate entity in the solar system and beyond; the traitor who cost Ben his wife, his future, and reduced him to a galactic renegade with no allies except a handful of star-wanderers and misfits. Dravis wants the universe and its vast, inexhaustible wealth. And he's unleashing a terrible new generation of weaponry and viruses, letting loose an unstoppable private army of drones, and mastering an indefensible system of mind control that will make his defeat all but impossible. In other words, taking Dravis down is the perfect job for Ben St. John, who wants his foe's head and has absolutely nothing left to lose. From the lethal labyrinths of Mars' Red Acropolis Research Facility to the unseen terrors of the Sirius System, Ben's ready to plow through all of his enemy's impregnable defenses -- just to prove to Dravis that old Marines don't fade away ... they keep getting in your face. less
