A Human settlement is destroyed and all signs point to an Yrmak raid as Imperial agents Tian Axmar and Brent Walker scour the site for clues. One thing they never expected to find was a survivor, a rare alien feline with unusual talents.

As tensions between Humans and Yrmaks ratchet to the point of no return, Tian and Brent must bring all their cyborg skills to bear as they follow a dangerous trail of deception and misdirection.

The feline, now dubbed Puss and strongly bonded to Tian, holds the key to many of the questions driving the investigation. Unfortunately, that bond drives a wedge between Brent and Tian's working relationship, leaving Brent with second thoughts about his decision to become a cyborg.

As the evidence unfolds, it becomes clear that a devious plot to incite an interspecies war will strike at the very heart of the Empire. With lives at risk, there's no time to waste. Racing against the clock, Brent, Tian, and Puss must stop the planned carnage, and this time for Brent and Tian... it's personal.
