Bach takes a lifetime of spiritual work and molds it into his eighth book, the one that details in depth his search for a soulmate. The author gives insight into the process of coming to terms with one's needs and desires.
All of Bach's works are in the non-fiction genre and revolve around his spiritual quests plus his lifelong devotion to flying. It is often said that flying is a metaphor for Bach's spiritual quest. The airplanes often tie in to where the author is at any given time. The more elaborate the plane, the more progress Bach is making in his journey. Smaller, more basic planes mean that Bach is starting from the beginning to reinterpret old ideals or start on a new path.
