Two voices intertwine in a duel of shadows: Hortensia, a convicted murderer confined in jail, delves into the darkest of her trades; Márgara, an elderly woman on the verge of death, understands her survival as a punishment dictated by the sins that silently haunt her.

What invisible force stops the murderous hand? What abyss opens between the compulsion to kill and the impossibility of doing so? In this psychological thriller, written with a powerful pen that combines meticulous psychological analysis with an intimate narrative overflowing with memories, the protagonists reach the verge of a silent breakdown, while the echoes of their inner corpses whisper words of anguish and pain in their ears, pleading for rest.

A story in which guilt and fear become characters, and redemption is merely a mirage on the horizon of consciousness. Each page becomes the prelude to a crime that repeats itself again and again without ever reaching its fateful end.
