This book has an interesting and unique concept -- relate the tales of similar people in different places and in different times. Unfortunately, it did not work for me as a novel. The characters are uninteresting. The settings are poorly constructed and unbelievable. The most vivid descriptions are of the Neolithic main characters having mad evolved-monkey sex, and it doesn’t make for much of a plot. The novel became so painful to read that I skimmed the last half, but I doubt I missed much. It did not appear to improve. ( )
