Mars stands at a crossroads. It can accept the tyrannical rule of the United Space Corporation, or pay for its freedom in blood. After Ambrose Drake's plan to free the red planet doesn't deliver the results he'd desired, he still hopes he can liberate Mars with minimal violence-until a brutal act of USC aggression makes it clear: USC will either subjugate Mars, or destroy it.

With his forces pushed onto their heels, Ambrose has no choice. To save his home, he must go on the offensive. He must travel to Earth and dismantle USC, once and for all.

But USC doesn't plan on giving him the chance. As they pit their might against Mars, they send someone after Drake: a ruthless assassin known as the Patient Dragon.

Now the clock is ticking. As Drake races to undermine the USC forces who oppose him, the Dragon grows closer with every step...
