The reader is key to the functioning of literature. But wasn’t in this way ever. For a long time the aesthetics bothered just with the author, leaving the reader aside. Today, is the reader that contributes in the constructions of narrations, giving a sense to them. This bring other implications. Arose the reader-model, author-model, indetermination points to be filled by the reader, that cannot be filled. Many times, the reading don’t satisfies the reader, because of the need to know to play the narrative game to understand it. Thinking in it, this paper has the aim of analysing the Uma certa felicidade tale, by Sonia Coutinho. Will be observed the reader and the author-model, how they are built in the narrative, as well as the memories of the principal character and their implications. It is a gap and confused narrative, challenging the reader to go ahead in the reading to have a better understanding. To the analysis it will be observed the concepts of Umberto Eco (1994), W. Iser (1999), VicentJouve (2002), Jauss (1979) and Henri Bergson (1999).
