When a vital member of the British millennials' mission goes missing after an intense firefight with Nazi-supported vampire hunters, Mors, the mission's powerful leader, vows to discover the truth behind his disappearance. The perilous search takes Mors from Berlin to his own ancient stomping grounds - Rome.

Mors was once one of the Roman Republic's greatest generals - until his rebirth as a vampire under unprecedented circumstances - and when he sees Italy under Fascism, he forms a new mission: to return the country to a true republic, and perhaps guide its people into the light himself.

As the Allies prepare to invade Italy, and hunters and Nazi-collaborators start to encircle him, Mors's quest for vengeance, intense passion, and hunger for power force him to confront the demons of both his past and present. A very different war is about to begin...
