The aim of the present study resides in a reading of the novel El guerrero del crepúsculo, of the Montevidean Hugo Burel (2001), in order to underline the dimension of rupture, fragility and deviation of contemporary urban centers and, especially, of the city of Montevideo. We will analyze the narrative modality adopted by the author to show the contradictions and discontinuities in the urban and social connective network of the Uruguayan capital; we will stress the importance of the relation that exists between the incipient desolation and the sensations of loss and uprooting that the protagonist experiences. The examination of the "no-goal urban walks" of the main character shows a timeless Montevideo, and exhibits a city in which the spatio-temporal modals seem to be distorted. We will put in relation this subjective distortion with the social invisibility of the protagonist, and we will try to explain it as one of the essential characteristics of the subjectivity and of the perceptive dynamics of post-modernity.
