En una ciudad costera del norte de Espana, Santander, una mujer joven se enfrenta sonando y delirando a la muerte; este extrano Teorema, definido con los pequenos encantos de su vida, la explica y aplaza. Por cuanto tiempo? Hasta cuando? Un hombre excepcional sera su sensible compania y vulnerable aliento; testigo involuntario de hirientes mentiras, amistad traicionada, desengano y penas. Un bello relato, ilustrado con originales oleos pintados, de su descenso al abismo; de su confianza en si misma, de su determinacion, y apasionada lucha; narrado en el diario de 21 dias intensos. *** In a small seaside town in Northern Spain, Santander, a young woman deliriously dreaming senses the presence of death. This strange Theorem, which she defines through the simple charms of her own life, explains and delays it. But for how long? Until when? Her exceptional partner brings sensitive companionship and vulnerable inspiration; an involuntary witness of hurtful lies, betrayals, disappointment and sorrow. A finely crafted short story, illustrated with original oil paintings, of her descent into the abyss; and of her self-confidence, tenacity, and passionate struggle; related in a journal of 21 intense days."
