After the death of his beloved wife, after the loss of his advertising business to his once-trusted partner, Alan Christoffersen is a broken man. Leaving everything he knows, he sets out on an extraordinary cross-country journey. With only the pack on his back, he is walking from Seattle to Key West -- the end of the map. Along the way, Alan begins to heal, meeting people who teach him lessons about love, sacrifice, and forgiveness. But in St. Louis, Alan faces another life-changing crisis, and now the journey is in jeopardy. Because his severe vertigo is diagnosed as the side effect of a brain tumor, Alan must go to Los Angeles for treatment. He is surrounded by those who care most for him: his father, who is happy to have Alan back in his childhood home; Falene, who has been by his side through his most difficult times; and Nicole, who helped him recover from a mugging in Spokane. One by one, Alan alienates them all, and he resumes his journey in angry loneliness. The people he meets as he walks the dusty southern back roads have lessons to teach Alan about accepting love. He just has to have faith that life can be worth living again, and that the woman he rejected will be willing to forgive him.
