The book started off promising, about a man and his dreams for total xenocidal warfare, with all the ethical and political problems thereof. Things were going along swimmingly and then, suddenly, about halfway through, the book changes tracks. Xenocide is no longer an option, and a whole bunch of other elements begin cropping up that weren't even hinted at before. Now there's a secret shadow darkity-dark conspiracy afoot that's been manipulating everything behind the scenes that made sure everything pointed the way towards xenocide, and they're pissed off that the book switched plotlines, too. Um, what?
It turns out the whole thing (the second thing, not the first thing) is just a ploy for the author to write a sequel. I think the book stands well enough on its own, but while it's an interesting universe, I don't see ever visiting it again. The author must have a history in serials; he continually goes over the same information again and again and again -- surely, the book could have been a good hundred pages shorter if all of that had been excised.
Nevertheless, it was an entertaining read, full of enough space battles and scientific explanation to satisfy all but the most die-hard of sf readers.
