My rating is 3.5 stars.
I enjoyed the first 25% of the book very much. The premise of using prehistoric sperm to impregnate a modern woman is interesting. My problem is that the story is disjointed with several major breaks in logic and reality. It is definatily an easy quick read for those times when you want to veg out in your reading. The writing reminds me of YA fiction. I wish the last 75% of the book would have been as interesting as the first part.
