This is why I so rarely start series books. The first book was great and the second book was awful. Farmer assumes that if everyone who ever lived was brought together on the same planet at the same time, everyone would constantly be fighting everyone out of sport and boredom. And, thus, Farmer created a very boring sequel to a great first book in the series. I just couldn't finish this. I was 100 pages from the end before I didn't care if Mark Twain ever managed to find all the raw materials to make a riverboat to travel down the river that passes through the planet. In fact, this book seemed as if it were written by an entirely different author than the first. While the first book in the series kept me turning the pages, this did the opposite. Good riddance!
