As more Undead are created, a second battalion is formed.

Pax becomes a team leader as the Marines are developing new tactics, but the Tucanans aren't standing still, either.

And they seem to have targeted the Undead. High on their list of priorities is to figure out what makes the Undead so dangerous, and they'll go to any length to get their foot-arms on a few of them.

Pax has to ensure their military mission is accomplished while blocking the Tucanans from taking Undead prisoners to face a fate worse than death—even multiple deaths.

Between the Tucanans, public outrage and alarms, and unpredictable command decisions, Pax and the Undead must navigate complicated and increasingly dangerous waters in their mission to save humanity.
