Book 1 wasn't a fluke, thank god.
This kicks off immediately where Book 1 ends, and maintains the same frantic pace, which was awesome. Dylan Kane remains a one-man killing machine, innovating novel ways for aliens to die, even as his own death seems more likely with each turning page. Unfortunately, the aliens seem to be innovating as well, which can't be good news for Kane and his dwindling squad of makeshift troops.
This is fast paced first-person military sci-fi set in a solar system of the near future overrun by little grey men who have subjugated humanity (we helped with that mind) as cannon fodder in their war against other aliens who look a lot like Neanderthals. Kane is learning some interesting about the who and what of that conflict, but whether he can survive long enough to take advantage of it remains to be seen.
Great fun, lots of guts and gore, this is one of those novels with characters that make you care - and some that make you want to reach in and punch them out, just because - without belaboring the point emotionally or slapping us about with page upon page of backstory. Really great fun, well recommended.
