Eight-year-old Aaron lives in a country called Premium on the planet Astron, but unlike his tall, perfectly purple family and friends, Aaron is round, small, and green. His classmates tease him and won’t play with him because he’s different from all the other Premiums. Why won’t they accept him for who he is? His only friends are the sun moonies and myrtle dockers, strange and wonderful creatures who live in the forest and teach him the secrets of the mysterious underground caves and tunnels. $8.49 on Kindle.
