What mainly attracted me to this book was the fact that it had won the Pulitzer Prize. Therefore, I assumed it was going to be excellent; however, I was very disappointed.
The plot had immense potential. There, supposedly, was the tale of the Castillo brothers, Cuban immigrants who come to New York hoping to "make it" as mambo musicians. They worked at a factory during the day, and worked at different clubs at night, and the tale was to tell of their daily life and neighborhood fame. The book's plot, however, centers around the "busy" sex life of the older brother Cesar, and the depression of the younger brother, Nestor... There is still, however, the faint story of the brother's fame. They become very popular in their neighborhood during the 1950s--the Mambo era--and manage to catch the attention of Desi Arnaz, who later invites the boys to appear in an episode of I Love Lucy (marking the heighth of the "Mambo Kings" fame and glory). After Arnaz, however, things fall apart and what's left of the Mambo Kings is old, tired, and pitiful.
While Cesar's sex life and Nestor's depression were the main plots, there were other shorter stories that really didn't fit...
In general, this book was poorly written (grammatical and spelling errors are everywhere), underdeveloped, and, at points, almost pornographic. It did not "move" me, and I never cared about any of the characters. This book was an extreme disappointment, and it's a wonder it won the Pulitzer. I wouldn't buy, or even read, this book.
