Probably my favorite author of fiction. The feast of the goat (la fiesta del chivo) is at the top of my list if you have not read him.
It's the first one of his books that I read and I remember being completely in awe at his ability to write a novel as if he had a machine that allowed him to look into the minds of anyone at any time or place and then document what he saw.
That novel is about a totalitarian system, that of Trujillo in the Dominican Republic, and it's eerie how I started seeing the little details of human behavior that enable it in the story elsewhere later as well.
Que en paz descanze.
