In this compelling, behind-the-scenes account, former top CIA officer and Cuba expert Brian Latell examines the extraordinary Castro brothers and the impending dynastic succession of Fidel’s younger brother, Raul. Exploring the brothers’ remarkable relationship, he reveals how Fidel and Raul have collaborated, divided responsibilities, and resolved disagreements for more than forty-six years—a challenge to the notion that the little-known Raul has been an insignificant player. The result is an intimate portrait of two enigmatic men and a new understanding of the psychology and motivation behind their actions. Based on his insider knowledge of Raul, Latell projects what kind of leader he will be and how the shift in power might influence US-Cuban relations.
