On Earth, the cities of humanity crumbled to dust, turning into fossils. Forests burned and life went extinct. But, billions of years later, it rained one last time. The siblings were born from that rain, strange creatures of human appearance and mind. Their life on the desert of Earth has no purpose, until they discover the wick, a molecule burning around their genetic material, condemning them to death one hundred years and three months after birth.

In search to find out if life is worth living, a researcher explores a cave on Earth billions of years old. The brain inside a simulacrum misses its dead father. The commander of a spaceship travels to meet a mysterious satellite orbiting Mercury, perhaps an ancient artifact that humans left behind before extinction.

In this story of philosophical dimensions, the power of the word merges with the nostalgia for an irretrievable past, where fear of death coexists with the sadness of losing the parents you will never see again.

A hard science fiction book dealing with topics such as molecular biology, stellar evolution and the future of Earth, combined with poetry, sculpture and the early artworks of creatures who yearn to be human.
