The second book of the "HOLLOWS" trilogy.
Following the failed experiments of Project REVIVAL, a chemist named Kean Santiago is faced with a predicament that could send the entire nation on it's knees. Roaming the lands are hostile, lifeless corpses that have gone berserk after exposure to the Revitaliserum, a formula supposedly used to bring back the dead to life.
In order to resolve the catastrophe, Kean tasked himself to acquire a chemical that could reverse the effects of the formula.
