"Abaddon", arguably Sabato's most experimental work, presents a fragmented narrative structure. It mixes autobiographical events – which combine actual events with fantastic elements – with parallel stories, philosophical analysis, hypotheses and literary criticism, retold by characters who, in the same role, were often present in the previous novel. "Abaddon" is arguably apocalyptic in tone, recreating adverse historical events that took place in Argentina in the 1970s, as well as mentioning twentieth century events, such as the Second World War, the bombing of Hiroshima and the Vietnam War.
