The smoke and ashes had cleared, but still the fog of the undead war lingered on. Since Yoon's death Sai had carried on, leading the military arm of the temple fortress Wat Tatsunupi in a never ending struggle for survival. Searching for reason, he entered the temple and stumbled upon the records the monks had filed away. There in the depths of pages are interviews, stories of those had lived and fought in his community since the beginning. The city spirals out of control as one last air assault into the city takes place. The countryside echoes with the bombardment at major choke points where the dead tsunami sweeps across the streets. Families are torn apart, friends pushed to the limits. The records go on and on but before Sai can continue reading, he finds himself airborne once again heading towards the dark unknown. Now all that stands between life and death is the helicopter fleet known as DEAD AIR.
