This book has a great adventure. The illustrations really set this book off. They give the book a clean crisp look and the dull cave paintings almost hide from your eyes as you read it. It is kind of a dull plot as well. It a plot like this is used so much in children's books. It has a dream like sequence at the end and you think it was all a dream until you see proof of what actually happened. I liked it but it was not anything special. I loved the boy in the story. He looks so innocent and the illustrator did a great job at making him look the part.
