Now, however, pirate attacks are on the rise again. When the Cadre ambushes a medical convoy under the protection of Brad Madrid and the Vikings Mercenary Company, the attacking warship turns out to be of a type and class the pirates should never have come into possession of. The Cadre is no longer limited to pirate corvettes and scratch-built destroyers. Somehow, they’ve come into possession of a modern fleet of warships no one outside the Commonwealth should possess. Brad Madrid owes the Agency and the Commonwealth his allegiance and his life. So when Kate Falcone calls on him to help seek out the Cadre’s new shipyard, he answers without hesitation. Their investigation, however, will draw his mercenary company into a newborn conflict unlike anything he’s ever faced before. less

The outer colonies are in revolt. One man will make himself Emperor. The Commonwealth must stop him…or fall. In the chaos after the death of President Barnes and the revelation of his betrayals, Brad Madrid has been imprisoned because of his relationship to the pirate known as the Phoenix.

Released from his prison and drafted into the Commonwealth Navy, Brad is sent out to wage war against his last living relative. As his own home, Jupiter, tries to step aside from the conflict, he finds himself with a sparse list of allies—and facing a far more powerful enemy than he’d ever feared.
