No tenía intención de escribir esta historia cuando la empecé, se escribió sola, y se trazó y entrelazó en la máquina de escribir. Acabó siendo la tercera de mis historias favoritas, entre todas las escritas.

LPodría decirse que Isaac Asimov, el mayor escritor de ciencia ficción que ha existido, poseía una de las mentes más brillantes y creativas del siglo XX.

Esta es la historia del genio paradójico que escribió sobre viajes a las estrellas y se negó a volar en avión; que imaginó universos extraterrestres y vastas civilizaciones galácticas mientras se quedaba en casa entre páginas.

Andrew Harlan’s job is to range through past and present centuries monitoring and even altering Time’s myriad cause-and-effect relationships.
