Book 2 in the Demon Squad Series.

Armageddon averted, the world returns to business as usual. Unfortunately for Frank "Triggaltheron" Trigg, business as usual sucks. His night out interrupted by a horde of kidnapping zombies, what could possibly be worse? The resurrection of the Antichrist, that's what. Caught in the middle of a supernatural pissing match between the devil's wife, a legion of undead, and an overachieving necromancer, Frank must survive long enough to stop hell from being unleashed upon humanity--again.
