This is simply pure bliss to read. There's plenty of action from the word go, its thrilling and most importantly its new. The idea, the concept, is new, its not fantasy fiction by numbers. He uses plain old violence, and guns as well as magic.
The hero comes back with a vengence based killing spree in mind and enjoys violence, stealing cars, cigarettes from hell, and he's the hero.
Stark used to hang round with a group of people into the occult in modern day L.A. but the leader of his group betrayed him and sent him, alive, to hell. The first live human in hell he was a novelty, harshly dealth with, who fought repeatedly in Hells arena's gladiator style against all manner of demons, he became hard to kill, then he became an assassin of Demons for one of Hell's generals and the denizen's of hell came to fear his name. Now he's escaped hell and he's after vengence on the people who sent him there.
The book starts with him crawling out of hell in a grave yard and the action starts almost imediately, the back story slots in arround the action so you don't have to endure a mass info dump back story. Its so riveting I literally read this, and the subsequent books in the series, start to finish in one sitting.
I won't go any deeper into the storyline as I dislike too many spoilers in reviews. Simple to say I loved this book. I felt the topic had enough original invention to thrill most people sagging from fantasy fiction by numbers. It was action packed from the first page, the hero is a dark violent hero who you will absolutely love and root for. The writing is fluid, has a fantastic balance of action and dark humour, and manages to balance story, humour and action perfectly.
