I thoroughly enjoyed this sequel to Superhuman. We continue with the same main character, now known to most of the world simply as, The Marine. The action is mostly non-stop, and completely over the top in the best way. Willful suspension of disbelief is a prerequisite.
This second offering has definitely stepped over from the superhero genre into military science fiction. While powers are in the offing, there is more detail about military organization than the powers themselves. This is not necessarily a bad thing, but it is worth noting.
At the time of my reading, the author was including a foreword that warned that the novel was being offered at a reduced rate because of needed editing. He wasn't wrong, errors abound in this version that were occasionally distracting. Eventually, an edited version will be offered, and it might be better to wait for that if you are distressed by grammatical errors.
All-in-all, a fun read, with interesting characters. However, this sequel seems a little less put together than the first book.
