Exodus Towers, by Jason Hough

A few weeks ago, I posted a review of The Darwin Elevator, the first book in Jason Hough's Dire Earth Sequence.  As I noted then, I think it's pretty cool that he is releasing this trilogy in rapid succession.  Book 2, The Exodus Towers, picks up where The Darwin Elevator left off.  Hough continues the hard-hitting action, brings the aliens more into the picture, and presents a whole new set of human conflicts.

In a follow-up alien event, a second space elevator appears in South America.  Skyler and a few others separate from the Darwin Elevator to establish a new colony.  Soon they face a rogue band of immunes, who try to take over the colony.  Then a new form of subhuman, enhanced by alien technology, shows itself.  Facing these new foes and trying to figure out how the human race can survive adequately occupy the time of the Exodus colony.

Meanwhile, back in Darwin, the Jacobites, a religious cult, have taken over the whole place, first through wily political maneuvering, then by force.  Skyler and company are working against the clock, knowing the Jacobite's desire to control both elevators, and knowing that there are more alien events coming, in quicker succession than the last one.

In terms of forecasting technological and societal developments, an important part of any sci-fi, Hough makes a couple of interesting points, both of which play into the story.  First, I noticed that in Hough's future earth, technology as a whole didn't seem adequately advanced for a setting 250 years in the future.  The main reason for this is that Moore's Law, which predicts exponential growth of processing power, proves to have its limits, and processing power plateaus.  Second, China outpaces the West, leaving Western Europe and the U.S. in their economic dust.  Why?  Chine embraced nuclear power, developing safer, more powerful, and longer lasting forms of it, so that "while Europe and America struggled to attach a solar panel to every roof and burned every last drop of oil, China and the developing world suddenly had no energy problem to speak of."  Soon, "Europe was still in catch-up mode, America was a distant memory."

There are a couple of spots where the story drags or skips without a lot of explanation, and some convenient plot elements thrown in, but, hey, it's fiction.  Altogether this is an exciting page turner, and the story adds to the epic feel of the Dire Earth sequence.  And the great news: only 4 short weeks until book 3, The Plague Forge, is released!
