Sign of Life

An astronomical observatory detects a strange emission from space at a frequency of 1.42 megahertz. A sign of life. The American government and the UN are immediately informed.
An object is heading towards Earth.

NASA urgently prepares an international space mission to meet the unknown craft. Tomás Noronha, the world's greatest cryptanalyst, is recruited to the astronaut team.

Thus begins the most unusual adventure of the great hero of modern Portuguese literature, a breathtaking story that takes us to the heart of the universe's greatest mystery. Is life an accident or does it result from a design? Are we alone, or are we one among millions of inhabited worlds?

Is existence a coincidence or does it have a purpose?

Sinal de Vida brings us José Rodrigues dos Santos, the Portuguese people's favourite writer, at the peak of his extraordinary narrative abilities. A thrilling novel that, through the thread of an intense and absorbing plot, questions us about life, its purpose, and our place in the universe.
