I read all kinds of books (one of my friends jokes that I will read anything that holds still long enough), but sci fi/fantasy is my favorite. I also love books on anthropology and archaeology and other sciences.
A good portion of the series, but it seemed a bit thrown together. I liked the concept of racism and slavery that was addressed throughout the book. While typical of sci-fi series, this particular one was well handled, of all the books I've read that deal with slavery and discrimination.
