Humanity's Last Stand. The Last Bastion, #4

This is the final war. The Carrion Pope has launched an apocalyptic offensive, bringing every horrifying zombie mutation to bear against the fortified walls of The Last Bastion. Commander Jarek Solborn must make the impossible choice to unite all available human factions, even offering a desperate, temporary alliance to his archenemy, the brutal Marshal Dren Korrik. With the combined armies of the Red Barriers and Commander Lys Varren's Reclaimers fighting alongside his heroes-Nash Vettor leading the ground charge, Vira Kael clearing paths with heavy fire, and Riven Strade providing air cover-the Bastion becomes the center of humanity's last stand.
Dr. Maren Vosel races against the clock to synthesize a biological weakness. The saga culminates in Jarek's direct, desperate confrontation with the Carrion Pope, a final battle that will secure humanity's future or doom it to extinction.
