The enemies is a book of nine stories of psychological and fantastic vein that explore three fundamental themes: the links with the maternal root, death and gemelity.

In several of the stories the overlapping of the mother and death gives rise to a tragic treatment; it is, therefore, the presence of a mother devouring the soul of the child, a manifestation of the enemy impulses that exist in every experience of motherhood and that society seeks to hide. In other cases, the absence of the maternal figure and its psychological consequences in individuals confronted internally by this lack are explored. Each story has a death as a gravitational center rather than as an end point; around that death - one's own, that of the mother, that of the daughter, that of the brother, that of the enemy - the characters are thrown into a process of psychological transformation, the basis of the plot of each story.

The enemy has as its secret structure the Aztec legend of Mictlan expressed in the Ríos Codex: the nine houses that the soul must travel to achieve eternal rest coincide with the nine months of human gestation, and each story is likely to be read as a fictional representation of each of these difficult passages of the human soul, in the context of life in Mexico at the beginning of the 21st century.
