Query: Don't waste your time

If you've already read the first book in this series then you know how boring Ms. Robbins writing is. Don't even read the back cover of this book, just pass it on by. There are much better pre-historic books waiting for you: Jean M. Auel, The Gears, Lynn McKee, Mary Mackey. I'd even say William Sarabande is better than Ms. Robbins (but not by much).
