Query: Zavalita and Ambrosio, who will win the battle?

Vargas Llosa created one of the best characters i've ever seen. Santiago Zavala lives his life at his own way, dealing with problems no one would expect he would have to go through. Leaving back his parents to make his own decisions and then, years later, face the past he never knew. Llosa's style is easy on all four books (each one owns a different style), which will help you to go through the saga without dropping the book, always expecting something new to happen.
