Omertà
Mario Puzo
 The book begins with the death of Don Zeno in Sicily. Don Zeno left his infant son, Astorre, with Don Raymonde Aprile. Don Aprile lives in New York, where he is known as a fair but merciless Mafia head. Aprile is a widower who does not want his children to follow him in illicit business. To save them, he sends them to private boarding schools and only sees them on holidays. Astorre is the favorite of his children, Aprile considering him his nephew, and Astorre is picked as the one who must protect the family after Aprile dies. Aprile decides to take Astorre, a young and bright child, to Sicily one summer. One day while the Don and Astorre are walking the streets of Sicily, a small cosca kidnaps them. The captors treat the Don and Astorre well, but they want a ransom. Aprile warns the kidnappers to let him go. "The rest of your lives will be miserable if you do not." The cosca does not realize how powerful Aprile is. In the middle of the night, Bianco, a friend of the Don, rescues Aprile and Astorre. Aprile wants to kill the kidnappers, but Astorre asks him not to. Aprile gives in, but makes the men his loyal servants. When Astorre turns 16, he has a romantic affair with Nicole, the Don's youngest child and only daughter. Aprile orders the boy to move to London, to attend college and stop the affair. Nicole is upset by this, but Astorre obeys his uncle without argument. Astorre stays in London for a year with Mr. Pryor, a banker friend of the Don, and then returns to Sicily, staying for ten years and serving under Don Bianco, an old friend and protector of Aprile. During his time in London, he meets a young woman named Rosie, with whom he begins a romantic relationship, which he continues during his time in Sicily, until he finds out that she has not been faithful to him. When Astorre comes back, having completed his training, Aprile decides it is time to retire from his dangerous business. He settles all his accounts and pays off all of his associates keeping only his ten international banks, which are completely legitimate. Aprile instructs Astorre that when he dies the banks should not be sold. Aprile writes in his will that Astorre owns 51% of all voting stock in the bank, with the Don's children owning the rest. The interests from the bank will go to Astorre and the children evenly. In the meanwhile, Aprile starts a macaroni importing business for Astorre. Valerius, Aprile's oldest son, invites his family to his son's communion. After the communion commences two men execute Aprile in a drive-by shooting. Without any public authorities securing the area, the killers are able to escape and, in spite of Aprile's power, there is no subsequent investigation into his death. Timmona Portella, controlling the only significant criminal organization remaining in New York, along with his international partners, tries to negotiate with the Don's children and Astorre to purchase the banks from them in order to launder drug money. However, Astorre, holding the majority share, consistently declines their offers, following the Don's instructions and claiming that he has found a love for the banking industry. At first, Aprile's children want to be as removed as possible and want to sell the banks thinking Astorre naive and innocent due to his good-natured and friendly demeanor, and while baffled that their father left him the majority share, want to protect him. As time passes, though, they come to see that their father had meant for his banks to secure their futures in their respective careers, and that they had done so thus far, with Valerius a high-ranking military officer, Marcantonio a prolific TV producer, and Nicole a successful lawyer in a prominent law firm. They also start to see that there is more to their "cousin" than they thought, and begin to suspect the reason why Aprile left him in charge. Drawing upon his years of training, Astorre methodically seeks each of the people responsible for the death of his uncle and had been trying to get control of his banks, consulting old friends of Aprile for advice. At times during these consultations, the friends suggest selling the banks to avoid all the trouble that Astorre is going through even to stay alive, but are impressed when he politely rejects the idea, seeing in him determination and strength that they themselves lacked. Astorre finds each of the people involved in Aprile's murder, from the hitmen to those who ordered the attack, and is able to eliminate them without detection by the authorities. Two years later, Nicole has taken over as general manager of the banks, and her brothers are working on a film for TV recounting the life of their father, with Astorre as a consultant to help them with some of the details. Astorre eventually decides to move to Sicily permanently, and there marries Rosie, They have their first child, whom they name Raymonde Zeno, after Astorre's two fathers, and they consider the day that they will bring their son back to America.
