Plot summary
Brasyl is a story presented in three distinct strands of time. The main action concerns Marcelina Hoffman; a coked-up, ambitious reality TV producer in contemporary Brazil, a striving amateur capoeirista who transcends the cliches of luvvy television phony and becomes a full-fledged, truly likable person as we watch her embark upon a mad new project. Marcelina is going to find the disgraced goalie who lost Brazil a momentous World Cup half a century before and trick him into appearing on television for a mock trial in which the scarred nation can finally wreak its vengeance.

Another strand is set in mid-21st century São Paulo, at a moment when the first quantum technologies are reaching the street, which industriously finds its own use for these things. Q-blades that undo the information that binds together the universe, Q-cores that break the crypto that powers the surveillance state that knows every movement of every person and object in Sampa and beyond.

The final strand is an 18th-century Heart of Darkness adventure in the deep Amazon jungle,  following an Irish-Portuguese Jesuit into slaver territory where he is sent to end the mad, bloody kingdom of a rogue priest who scours the land with plague and fire. He is joined by a French natural philosopher, who intends to reach the equator and discover the shape of the world with a pendulum.
