A mouse is swallowed by a wolf and, to her great surprise, encounters a duck in the wolf's belly. The two have a splendid conversation, celebrate a feast, eat to their fill, and philosophize about the pleasures of being eaten. For those who have already been eaten need not fear such threats anymore. In the end, the two accomplices even manage to save the wolf from a hunter, thus defending their safe and cozy home. The well-known American children's author Mac Barnett provides us with an exceedingly original explanation for why wolves howl. Jon Klassen illustrates with skillful simplicity and unparalleled sharp wit.
