El Pozo by Juan Carlos Onetti

A solitary, disillusioned narrator recounts his aimless drift through life, recalling failed relationships, humiliations and missed chances while wrestling with memory, guilt and a profound sense of estrangement. Told in a sparse, introspective voice that blends bleak irony and lyrical detail, the book unfolds as a fragmented interior monologue that probes existential loneliness, the erosion of identity and the impossibility of meaningful connection.
