Second book int he series about a human colony fighting off an alien invader. If you didn't like the stock characters and simple triumph of the spirit story from the first book then you probably won't like this one either (and vice versa).
May 2022: I wish I could remember the first time I read this sci-if trilogy, ages ago, the 1990’s; I enjoyed the straightforwardness of the series then, and it’s allowed me to revisit it, and enjoy the experience all over again. This time a couple of things struck me. The first book is the best, laying out the basic premise of the book, the sci-if elements and defining the enemy. However, the overall all trilogy is plagued by a few problems. We don’t really learn much about future human society beyond a three worlds, and so the world building lacks. Second, the author ends up psycho-analyzing the heck out of the enemy aliens and ruining their mystique. Third, the unrealistic presence of the protagonist’s wife on the ship during missions and battles, totally ruins the military sci-fi setting. In fact, reading the trilogy this time I was surprised by the intensity of the romance between the two main characters, it felt distracting and out of place in these books. Finally, when I first picked up these books in the 1990’s I was areligious and thus, didn’t notice the author’s clumsy handling of Faith in this book. In the 1990’s Faith was still very much a part of most people’s lives, even a secular materialist, like Mr. McCollum, so he mentions faith, but mishandles it on the macro (it’s place in inter-planetary politics) and the micro (it’s place in ordinary people’s lives). The bottom line is that this trilogy does two things well: interplanetary travel sci-if, and hard sciencey space battles; everything else is clumsy or confusing. I only noticed these problems because I’m ten years older than the last time I read these books.
