Kalamari Outpost 9: Toxic Times Two.. Kalamari Outpost, #9

Blood, betrayal, and a nation in ruins. Following the destruction of the Dark Devil Pack shrine, the legendary mercenary Wolf Starscope infiltrates the impenetrable Fort Vikström on a desperate rescue mission. What she finds is not a comrade, but a gruesome abattoir...and the butchered remains of her mentor. As the Company of Silence scientists pay the ultimate price for their savagery, a horrifying biological safeguard is triggered, a purple transmutation virus erupts from a corpse, beginning to consume the prison itself.
Meanwhile, the horizon burns as General Akashi's Kalamari Outpost forces launch a full-scale invasion of the Poljak Ice Plains, indulging in a brutal campaign of total eradication.
