Pax is the highly anticipated new middle grade novel from bestselling and award-winning author Sara Pennypacker—a poignant and timeless tale of love and loyalty between a boy and his fox, set during wartime.

Pax was only a kit when his family was killed and he was rescued by “his boy,” Peter, from abandonment and certain death. Now the war front approaches, and when Peter’s father enlists, Peter has to move in with his grandfather. Far worse than being forced to leave home is the fact that Pax can’t go. Peter obeys his stern father and agrees to release Pax back into the wild. But before Peter makes it through even one night under his grandfather’s roof, regret and duty spur him to action; he sneaks out into the night, determined to find his beloved friend. This is the story of Peter, Pax, and their independent struggles to return to each other in the face of war.

From bestselling and award-winning author Sara Pennypacker comes a beautifully wrought, utterly compelling novel about the essential truths that define us and the devastating costs of war. Pax is destined to become a classic, beloved for generations to come.
