Isso pode ser Kéthani por Eric Brown?
It takes an alien race to show us what humanity truly is. This is the irony faced by a group of friends whose lives are changed forever when the mysterious alien race known as the Kethani come to Earth bearing an amazing gift: immortality. These superbly crafted episodes deal with human emotions in the face of the vast consequences of the alien arrival, and show how people across the world react to this benign invasion, how ultimately we evolve as we gain the stars.
