"Psicología negativa y otros relatos" is a collection of short stories that make up a true aporia: tales of mystery and intellectual lucidity; urban and indigenous, intertextual and self-referential; about adolescence and adult life, as well as a short letter and the first pages of a novel. "Essays on literary criticism" brings together works of literary exegesis on three authors of universal, Latin American and Peruvian renown: Vargas Llosa, Monterroso and José Adolph. It is a brief hermeneutic and stylistic analysis of works such as "La guerra del fin del mundo", "El eclipse" and "El anti-bestseller".
