Pax by Sara Pennypacker

Peter rescued Pax the fox when he was little after his family was killed. From that moment on, Peter became “his boy.” When Peter’s father enlists in the war, Peter is sent to live with his grandfather and forced to release Pax back into the wild. Guilt immediately washes over Peter, and he sets out to find his beloved friend again. Will the two reunite or will Pax be lost forever?
