Query: Can't hold my interest

I read the first 3 books many years ago and loved them. I simply could not get into this book. The characters seemed much too modern day to be set in a story about the stone age. Very repetitive information, reiterating thoughts and occurrences multiple times chapter to chapter. I was profoundly disappointed. I'm almost halfway through the book and have simply moved on to other reading entertainment.
