After John realizes he can communicate with other corpses and angels, he begins a journey to enter a new stage of life. When it is decided he is not good enough for heaven, John is renamed Adam the Lonely and released to a wilderness park where he and his beloved cat, Panther, can spend eternity together. As he and Panther embark on a quest to find and adopt misplaced animals, they transform into a close-knit family who encourages each other to develop into better souls. The Best Friend in My Life is the poignant tale of one man's journey from life to death and finally to a wilderness park on the other side where he reunites with his beloved pet and finds the family he has always desired.
