The books in this series tell the story of ten children, all five years old, who are culturally diverse, and wonderfully bonded in friendship. They are found on a mysterious island, shaped like the palm of your left hand. In each book the children explore a different part of the island, which represents a different part of the world, with its unique wildlife. However, throughout the adventure they run into some fantasy and mythical creatures -- some good and some not so good.

In this book - The Upper Gulf Adventure, the children specifically explore the wonders of South America. They meet some of the most fascinating animals normally found there, and learn a few words in the native language. But then the adventure ramps up. They are repeatedly warned to avoid the Pointer Stream. Concerned animals give the children some interesting clues to guess about the monster. What happens next is an exciting eruption of mythical creatures that you'll just have to read for yourself.

The books are intended to be read to non-readers, but they are so captivating, that they appeal to young readers as well. The books are designed to be as much fun to read as to listen to, with appealing story line, rhyming cadence and songs.
