Amazon, 1541. Captain Francisco de Orellana leads a reduced expedition down an unmapped river in search of provisions. They do not return.
What survives is the record.
Four men keep their systems intact as the river refuses to correspond to their maps. The captain continues issuing orders. The surgeon continues diagnosing. The friar continues filing scripture. The chronicler continues writing. None of them stop. The horror is not what the river does to their bodies. It is that their systems persist long after reality has ceased to support them.
Rio Incognitum is a novel of bureaucratic dread and archival collapse - a colonial expedition narrative in which the record outlasts its archivists.
