Cyborg samurai Catherine LeBlanc pulls out the big guns—literally—when aliens unleash an apocalyptic weapon in the seventh book of this cyberpunk adventure.

The Antithesis want nothing more than to consume other worlds, altering their environments and birthing armies of monsters to continue their spread across the galaxy. Their next target is Earth, but with hundreds of Samurai protecting their home, it will be no easy victory. Taking root on Mars and its moons, the Antithesis have concocted a plan for the ultimate cosmic takeover: transform Phobos into a living satellite and hurtle it toward Earth.

Phobos has been terraformed into a breeding ground, creating an army capable of flooding the entire solar system. As the giant alien nest nears, the threat becomes increasingly apparent. If the Martian moon collides with Earth, the loss of life will be catastrophic, and the Antithesis will be free to turn humanity's home into a new hive for the enemy.

With Armageddon fast approaching, Catherine LeBlanc and her fellow Samurai only have a matter of days to prepare their counterstrike. To prevent the planet from turning into a wasteland, they will need to assemble international forces and meet their extraterrestrial foes on the battlefield. But even their combined firepower might not be enough to defend against what lies ahead....
