Like a lot of people, by the time I got to the end of the book, I just wanted to fling it across the room.
-----Here be spoilers--------
The entire premise of the book is that humans evolved on a planet called Minerva, which was in an orbit somewhere between Mars and Jupiter. The humans were descended from hominids brought over by space aliens millions of years ago. Some 50,000 years ago, these people had a war and blew it all up, leaving Minerva completely destroyed. The remains of Minerva become what is now the Asteroid Belt.
When Minerva was destroyed, its moon, having a colony of humans, somehow made its way to Earth and settled into an orbit around it. This moon is the Moon we see in the sky at night.
Never mind that millions of years of evolution has made life on Earth adapted to a moon that causes tides and shines brightly at night. Hogan's plot needs for us to have a moon that has only been around for 50,000 years!

I thought I'd give it a go, though, and the copy of Crypotnomicon I ordered last week should be here soon.
