Ernesto Durán is convinced he is sick. It becomes an obsession far exceeding hypochondria, and when Dr Andrés Miranda gives up responding to e-mails, Durán resolves to stalk him. Meanwhile Dr Miranda is coming to terms with a tragedy of his own: his father has been diagnosed with terminal cancer, and yet the doctor - the son - finds it impossible to tell him. He hopes that by taking his father on a trip to Isla Margarita, where they once went when he was a child, he might be able to reveal the truth. The nature of sickness as experienced by two individuals provides the backbone to this tender, thoughtful and refined novel. The Sickness is profound and philosophical, and yet written with an agility that expresses the tragedy, but also the comedy of life itself.
