This paper studies the novel Amarás a Dios sobre todas las cosas (2013), by Mexicain writer Alejandro Hernández, and proposes to go beyond the press treatment of the issue by offering an analysis of the fiction which focuses on the migratory journey. The testimonial value of the story reflects the full drama of that journey, allowing it to act as a tool of denunciation. Moreover, the story is presented as a chronicle, which allows the work of fiction to insert itself in a context that reveals the violence that Central American migrants suffer during their hellish crossing of Mexico.
