"Monkeys are Made of Chocolate is a tapestry of stories as rich as the land from which they came. Whether you like reading about huge snakes which always seem to come in pairs, the intelligent behavior of sloths, the ancient craft of boat building by digging out a tree trunk, or how toucans aren't quite as cute as they appear, this book is a treasure trove of Costa Rican life and natural history."

"In this well-crafted selection of short stories, Jack conjures up the intricacies of the natural world as only one who has been deeply imbedded for decades can do. In the manner of a master storyteller, Jack Ewing mesmerizes us as he takes us on wonderful trips in and around the rainforest. A must-read for anyone who has ever been in a rainforest, or is planning on visiting one."

"The serious underlying theme of ecological consciousness and responsibility is attacked by Mr. Ewing with grace and a healthy dose of humor. Instead of preaching he shows us through real stories and highly imaginative characters the havoc that we are wreaking on our only Planet Earth."
