Eddie and Minx live on a rather lonely island with their Aunt and Uncle and a wacky parrot friend named Paprika. There is a secret about their parents that they are very curious about, and the plot centers on their quest to uncover this mystery. Despite the threat of banana stew as punishment, they decide to investigate. Their quest takes them around the world discovering new lands and people, and learning about wildlife. The characters are lovely and well-developed.
Minx is the more cautious and pensive of the twins.
Eddie, on the other hand, is very excitable and impatient. After each chapter, there are a few games to play. Kids do various activities which include answering multiple choice questions about the chapter just read, memorizing country names from a map of the world, solving problems, learning facts about islands, telling time, and more. There are 48 games in all. Kids are required to get everything correct in any given game, or they are forced to do the entire game over again.
