Starting from some "premonitions of disaster" during his honeymoon in Havana, the narrator seeks their explanation in the past, although he prefers not to know, because he knows how dangerous it is to listen and that, once something is heard, it can no longer be forgotten.

One of the masterpieces of modern Spanish literature, "Heart So White" (Spain's Critics' Prize 1993, nominated for the European Literature Prize 1993, IMPAC Prize 1997) is a clear philosophical novel about the power of words and their ability to change the life of those who hear them, about secrets and their potential usefulness, about marriage, murder, encouragement, suspicion, about speech and silence, and about the very white hearts that gradually get stained, learning what they did not want to know.
