I have read the first two books in the series and it was entertaining for a while. But not for long and the books rested on my shelf for weeks, before I read another chapter and dropped it again after some reading.
The main protagonist is - as Royce had already mentioned - insane but it is fun too read about his trains of thought in some chapters.
I didn't like the world building at all, it is a apocalypse version of our current world in a future after a big downfall, where some mythologies of our history has survived ( such as viking and roman gods, greek heros, etc... ). Also the characters mention books about Platon, Sun Tzu and so on. I found it quite.... irritating at times.
The story is ok, but only driven forward by the main protagonist and his crazy actions, the other characters are mainly stereotypes and not very interesting in my opinion.
