'Aliens Invade Earth' is probably one of the most prevalent story ideas in the history of science fiction. At this point in time, an author had better have some new twist to the subject and write it well in order to justify going down this well worn path. Unfortunately, Mr. Dietz's twist isn't good enough for me to recommend it to others.
Earthrise is the sequel to Deathday. I'd received Earthrise as a gift, discovered it was a sequel, and decided that I should see if I should buy the first book. Almost all of the reviews I read of both books rated them both at fair or poor. After reading a summary of Deathday I realized that I didn't need to read it before Earthrise. I picked up enough from the summary to know what the scene was: Earth had been invaded by insectoid aliens and was now enslaved.
Dietz's twist was that the insectoid aliens were racist. In their hierarchical society, black bugs ruled, brown bugs were warriors, and white bugs were slaves. As such, when the bugs enslaved humans, they categorized them that way as well. For example, the black governor of Washington state is picked by the bugs to be the US president.
So why did the bugs (who call themselves 'Saurons' - not too obvious that they're bad guys) invade Earth? They needed to reproduce. Apparently the entire species reproduces asexually at death, giving rise to a nymph that carries the genetic memory of its parent. It's an intriguing concept but every single bug all at the same time? That sounds far-fetched to me.
In Earthrise, the President leads a resistance movement to take back Earth at the point when the bugs are spawning their nymphs. The humans are aided by another slave race that the bugs have brought with them through space. They're called the Ra 'Na. Their physical description makes them sound like otters, but they're a technically adept race who know more about the functioning of the bugs' starships than they do.
So why the need for slaves? Well, the bugs have this millennial tradition of building great pyramids where the spawning is to take place. And tradition dictates that slaves have to haul large blocks of limestone into place, no superior technology allowed. Once the pyramids are built, the bugs plan on killing all but a handful of slaves, just to make sure that no one attempts to kill the nymphs while they're still vulnerable.
There are a lot of questions that I have regarding the bugs. Do they have an endoskeleton capable of supporting their massive exoskeletons? If not, why don't they collapse under their own weight? How did this spawning technique arise? And why only one nymph? If a whole species is spawning at once how did they come to their present size? Why weren't they eaten by predators on their homeworld millennia ago? Maybe the answers to these questions are in the first book.
As for writing style, Dietz jumps all over the place. One page you're in Washington state, the next you're in Guatemala, and then you're in space on the bug ships. And so many characters are introduced that few stand out. Just as one character starts to be developed, he/she disappears for 40 pages. The end result is that the characters seem like cardboard props on a cluttered stage.
I was leaning towards a 2 star rating but the ending was a letdown. I kept waiting for the book to build up to a climax but it never really happened. When it ended I actually said, 'That's it?!' The whole book reads like a series of events just strung together. There's no ebb and flow of drama. I never got the impression as I read certain events that they were pivotal moments in the book. It's only now that I've finished it that I can realize them for what they were. It was like driving over speed bumps when I should've felt like I needed to swerve to avoid fallen boulders on a mountain pass.
In summary, if you're looking for a good alien invasion story, pass on this one.
