Sarah Fletcher is a nine-year-old student at Euclid Elementary School. She is like most girls; she likes going to the mall, hanging out with her friends, and listening to music. Sarah had no idea that a surprise gift from her Uncle John was about to change her life.

Johnny Maguire is a ten-year-old student at Euclid Elementary School. While enjoying a summer vacation in Florida, Johnny overheard two men plotting to destroy the dolphins so the dolphins cannot be used to detect their new weapon. Johnny teams up with the Geodes to try and stop their evil plot.

The Geodes are geometric super heroes from the twelfth dimension who get stuck on earth after an experimental gravity machine transports them to earth. While teaching mathematics at Euclid Elementary School to earn money to build a new gravity machine, they meet Sarah and Johnny and the adventures begin.

The Geodes series of illustrated children’s books teaches that mathematics can be fun and has many practical applications. Through the Geodes, the stories provide examples of everyday objects that are actually shaped like geometric solids. The Geodes also teach valuable life lessons such as crime doesn’t pay; honesty is the best policy, and the importance of teamwork and planning.
