The Amethyst Ring is the third book based on two previous books. The book is based upon a legand from the ninth century A.D. It follows a god from Maya named Kukulcan. The book talks about how once Kykulcan leaves Maya his travels through other parts of the world. He leaves to help Julian but his powers are not enough.

I thought the website that listed all the books by Scott O'Dell would be very helpful for teachers. He has a creative way of writing and by putting in history with fiction draws children into his books. http://www.scottodell.com/booksalpha.html
