Since this is sadly so rare among self-published books that it pretty much requires mentioning, I'll start by saying that Enemy of Man is well edited. More notably, however, it's also properly constructed, not only in terms of the action, which keeps escalating and eventually explodes in a manner which may, in itself, be almost overwhelming, but also because greater depth and complexity is revealed to the reader as the story progresses, the characters develop, the scope expands from the initial focused heroic tale, and bits of information about the huge and intriguing planet, multiple intelligent and semi-intelligent species and even the galaxy itself begin to be presented.
The problems start from the fact that the heroic tale relies too often on the hero's luck and at times makes even less sense than that in order to allow survival, yet the bigger issue is that this greater complexity and scope is mainly only hinted at, too little actual information about the planet, the species and the events, past and present, being provided. As a result, when it should all come together, there's little reason to care, and I for one felt that the great escalation, in itself somewhat similar to events which in other books were capable of moving me to tears, pretty much only got in the way, halting or at least being a frustrating complication in the way of the story of the characters that I actually had at least some reason to be interested in. Therefore, while I obviously recognize at a rational level that species and planets and the galaxy are infinitely more important than any characters, I have little interest in the bigger story I gather the rest of the series is about, because this first book failed to make me feel involved in it.
