In search of lost fathers - Latin American fiction

Is it just a random observation or is it true that a lot of contemporary Latin American novels center on a young person's efforts to learn about the past of his parents, parents who usually were involved in some manner with political upheavals, either as resisters against or collaborators with the autocratic dictatorships? I wish I could list novels that are exemplars of this vast generalization - seems to me some works of Bolano, and certainly My Fathers' Ghost is Climbing in the Rain, by Patricio Pron, which I read last year and with which I was very impressed. I'm now about half-way through Juan Gabriel Vasquez's The Sound of Things Falling and am seeing the outlines of a similar plot: we know little about the background of the narrator, Antonio Yammerer (sp?), but, well, here's a brief synopsis: Antonio was with a pool partner, about whom he knew very little, when the man was assassinated on a public street - and A. was shot as well. The "mystery" of the novel is: why was this man assassinated, and was A. just an unfortunate bystander? We learn that the dead man was waiting for the arrival of his estranged wife, flying in from the U.S., who died in a plane crash; immediately before the assassination, he had a tape cassette of the black box recording, which he played and burst into tears. Later, A. hears this tape. What is the connection between these two events - the plane crash and the shooting? And how would the black box recording be released to the victims' families? The heart of the story is A. difficult recovery - physically and emotionally - from the shooting. His girlfriend was pregnant at the time; now, we move a few years forward and we see that A. is still in some kind of shock, very bitter toward his girlfriend (I don't think they've married), and we learn as well that he has been impotent since the shooting. A. gets a message from the daughter of the dead guy, who wants to meet with him - he drives out to her house, a few hours from Bogota, and they discuss the black box tape over lunch. She's on a quest to learn about her father's death. The relations between the disparate, odd elements of this plot are hazy and obscure, but Vasquez seems a very competent and controlled writer and I suspect the smoke will lift.
