I read this book for a university course between 1993-97.
The narration is hectic & fragmented: inner thoughts mixed with straight narration mixed with flashbacks, run-on and choppy sentences, funky grammar, etc. I think it would be classified as postmodern.
PLOT: In the U.S., a wealthy, young woman goes to college and meets leftist/radical students who tell her about atrocities taking place in a Latin American country run by a military dictatorship. The young woman's father has business dealings with this country and her family’s wealth is linked to its oppressive regime (she grew up with an idyllic view of this country and knew nothing of the regime's violence toward its people). The final act: her father is hosting a party where a big-shot from this country (I think it’s a high-ranking military official) is the honoured guest (I think she met him before, as a kid or teen). She goes to the party wearing a loose, flowy dress (white with folkloric embroidery) that conceals the fact that she has strapped explosives to her body. She reaches out to embrace the General, hugs him tightly, and then detonates the bomb belt.
One other thing: the narrator describes the young woman as desperate for her father's attention and validation; he views her as a shiny trinket at best. The narrator likens the young woman to a begging puppy, writing something like "wuf, wuf, daddy" -- and this refrain sometimes recurs in the text.
I assume it was published before 1993. And I suspect it was published after 1970: the female protagonist has similarities to Weather Underground radical Diana Oughton, who died in 1970 when a bomb she was building blew up in a Greenwich Village townhouse. There are so many parallels that I can't help but think that the author used this real-life person as partial inspiration for her character.
