Daemons and angels, vampyres and knights, clash for the future of mankind, and as the two sides wage war across the world, innocent people are caught up in the conflict - men like Captain William Saxon and Lieutenant Kieran Harte, two great friends who have recently survived the horrors of the Battle of Waterloo.
In a heart-stopping race against time, the soldiers must battle murderous militiamen and daemons, and finally, terrifyingly, the bloodthirsty Guardians of the Horde. If William and his men fail, the agents of Hell claim the Hoard. And then they will unleash an army of invincible daemons, and humankind will come to know the meaning of evil.
