From celebrated New York Times bestselling author Steve Berry comes the latest installment in his wildly popular Cotton Malone series --- an adventure that takes Cotton to Italy and Tuscany to solve a five hundred year old mystery.
*
Cotton Malone is on the hunt for a forgotten 16th century Pledge of Christ - a sworn promise made by Pope Julius II that evidences a monetary debt owed by the Vatican, still valid after five centuries, now worth in the trillions of dollars. *But collecting that debt centers around what happened to the famed Medici of Florence - a family that history says died out, without heirs, centuries ago.* Two more things also hang in the balance. *Who will become the next prime minister of Italy, and who will be the next pope. *Finding answers to all three proves difficult until Cotton realizes that everything hinges on when, and if, the Medici return.
