The main character of all three novels is Dr. Victor Hunt. All in all, your average science fiction hero scientist. And he has that annoying ability to come up with solutions that are so simple and obvious that everybody else looks stupendously stupid for not figuring it out. I like him, probably because Hogan manages to make me feel nearly as clever as Hunt. Soon we have a couple of bases on the moon and manned probes all over the solar system.
Hunt is set in charge of figuring out where the body came from and what it's doing on the moon.
As if that wasn't enough we also discover a twenty-five million year old alien spaceship in the ice on Ganymede. Dr. Hunt is never going to get bored. Well, no, but you will be cheating yourself if you don't. The mix is a bit too heavy on the essay side for me, but that doesn't make it a bad book as Hogan has some very interesting things to say. Taking the butterfly effect to the max.
