It's an unbreakable defense versus an unstoppable assault!

Decades after Bull took control of the long-abandoned facility on the moon of Tambu, it has become a refuge, a weapons manufacturing facility, and a holding point for The Company's varied assets. It has remained one of The Company's closest-held secrets.

It is not a secret anymore.

With the fleet overwhelmed, casualties piling higher and higher, and the defenders all but eradicated, the Science Guild believes they have free rein. The Guild is wrong. They didn't count on Ruxandra Roxtador, a mostly-retired Pushtal spy, a small cadre of living science experiments, a trio of fearless Flatar, and Lucille, the base's synthetic intelligence.

They will hold the facility at all costs, or die fighting.
