Query: COOL!

This book is great! We are studying Cro-Magnons in our social studies class now and were asked to read this book. I think it is cool that the author wrote this whole story using only the information in the book. Although we know the characters in the story are fictional, Marjorie Cowley didn't give us any information that isn't true or that she is unsure of.
