Query: Dreary

Jean Auel has written 5 books in this series. This one is the poorest. It drags, page after page, it drags. It is repetitious to the point where I skipped whole paragraphs. Much of it is re-hashes the previous books. The sex appears to be added as an afterthought to relieve the boredom. I kept hoping, but nothing ever happened that grabbed my attention. "Valley of the Horses" was fascinating, it sits in my bookcase and I'll re-read every couple of years. Shelters of Stone I'll donate to the local libary.
