Boca de lobo (Chejfec 2009) speculates on the transgression of physical and imaginary borders, both at a geographical and corporal level. Taking the novel's argument as a starting point, the objective of this essay is to analyze the border transgressions occurring both at the geographical and corporeal space. Once these representations are identified, I propose to evaluate the possible correlation drawn by the narrator between one space and the other, that is: to interpret the movements through physical and imaginary boundaries, as to identify the extent to which subjectivities can be affected by space.
