In An Unfound Door, Gabe evolves from a shy, sickly loner to a thoughtful, empathetic young man as he makes his way through the turbulence of 1960s America, beginning a quest to understand the purpose of his existence and the mystery of his recurring dream. His journey takes him along winding mountain trails and on hitchhiking adventures far into Canada. He experiences love and loss, finding wisdom and friendship in the words of a Chinese shop owner, a Blackfoot elder, an imam, and an old widower the locals call Tommy Trashcan. His path eventually merges with that of his best friend, Manolo, and together they search for answers in the confused and chaotic sixties, encountering a mysterious biblical hitchhiker who saves them from a dangerous situation. At last, the meaning of Gabe's recurring dream becomes clear, as he and Manolo walk a path together into a new world.
