This is a fun listen, but one has to enjoy the tongue in cheek and very unrealistic style. I mean the character is named Adrian Hell so what did u expect ? This guy is ridiculously invincible but hey why not. He has a likeable personality which is why it works. The actual story and weapons and motivation etc. needed to be better though, it lacks substance. This detracts from being a better book. The narrator is excellent, getting the tone right.
