Genre: Space Opera.
I think this means that the book is more about action , combat and thrills than science, character building and deep thinking. SLAVER Wars, Alien Contact is all about what happens when an advanced , peaceful, expansive human society encounters a more advanced alien and definitely not peaceful society. The results are not pretty, but it does make for some exciting moments.
So, why three stars? The characters are all typical. The strong, valiant Admiral, leader of the resistance. A weasley, pompous politician who wants to negotiate with the aliens despite their obvious blood thirsty nature. A tech whiz female officer who falls in love with another office just as everything is going up in radioactive smoke.the dialog is banal. Description of the warships, weapons propulsion and communication systems are brief and relate pretty much to common current terms anyone who has watched the Star Trek vids will be familiar with, so scientific jargon does not get in the way, The aliens are "reptilian" but look much like humans.
Does it matter ? The book is a western ,set in outer space, with the white hats, sneering villains, and tough townspeople waiting for the cavalry. And like those Western movies of too long ago, the book is entertaining, with a slam- bang fight at the finish. In fact, it was that battle at the end, along with a few surprises to tweak the plot that made the book worthwhile.
For fans of the genre, be advised, though. Slaver Wars, Alien Contact is no. 1 of a series at leads six books long, so sve up your pennies if you get into the fate of our heroes.
