"I need your help, Mark! You're the only one that can do it, man!"
At first, Shane's request seems simple. "Be a judge in the Nabukur. Help guide souls to their final rest in the Irkalla."
Feeling he has no other choice in the matter, a newly deceased Mark agrees to help his friend and accepts the offered position.
Although it takes a while to get used to his new occupation, Mark eventually believes he's made the right decision. He likes being able to help souls find their intended afterlife. And, more importantly, he likes being thought of as the good guy for once.
Unfortunately, that all ends when a malicious spirit escapes the Netherworld and reenters the mortal realm.
Told he's the only one that can retrieve the fugitive soul, Mark reluctantly returns to the world of the living. Taking up his former job – that of a supernatural hitman – he immediately begins the task of tracking down the malevolent specter in hopes of sending it back to Hell.
Can he locate and expel the soul-stealing creature? Or will Mark Castle be the next victim of the power-hungry witch?
