The 1960s-1970s were turbulent times. Brooklyn, New York, and Vietnam were the backdrop of Marco's journey through love, war, Mafia, and street gangs. He and his friends got strong and fought back. Marco and Francesca were madly in love. But her Mafia family interfered with the fulfillment of their tormented relationship. Marco found solace in music. Marco and his friends saw hell in Vietnam. Some died. Felix Lopez fell in love with Thien Lan. The pullout of America from Vietnam devastated their lives. Felix fought many odds to be reunited with Lan. The Mafia's secrecy ended with a flashy, new Godfather. Author Carl Turco has written a handful of books. This novel is his second published work. His first published book, Enterprise Architecture & Metadata Modeling, is an Information Technology treatise on how to best design Enterprise Data Models and Enterprise Data Bases. But Carol is more moved by Many Shades of Gray, because in his view, a description of innovative Technology does not compare in creativity to a reflection of the human heart, as related to the intense love and pain a human being can feel. In this novel, Carl brings value added with music and philosophy: enriching concepts to the human spirit!
