From the author of The Bully Book comes a timeless story about a young boy, his father, and the world that comes between them, which New York Times-bestselling author Peter Lerangis called "magical, mysterious, fresh, original, and full of heart."

Marlin is not slow, or mute; what he is is a stutterer, and that makes it impossible for him to convince people otherwise. What he is also is a Rackham: the younger son of the world-famous explorer Ronan Rackham, the owner and proprietor of the Zoo at the Edge of the World, a resort where the well-to-do from all over the globe can come to experience the last bit of the wild left at the end of the nineteenth century.

In order to impress a powerful duke who comes to visit the zoo, Marlin's father ventures into the jungle and brings back a mysterious black jaguar, the only one in captivity. Everyone is terrified of it, including Marlin--until one night, when the jaguar confers upon him a powerful gift. Soon, Marlin finds himself with a difficult choice to make and, finally, something to say. If only he can figure out how to say it.
