The novel “Axis” by Robert Charles Wilson was published for the first time in 2007. It’s the second book of the Spin trilogy and follows “Spin”.

Humans are colonizing the New World, and many of them have no problem with the presence of the Fourths, but the “Department of Genomic Security” is still trying to track them down, particularly a group that used Martian technology to create a very special child.

Meanwhile, Lise Adams is investigating the circumstances of her father’s disappearance ten years earlier. Among the clues she has is a photo of him with some Fourths, whom she is seeking on the New World to ask for help.

In his novel “Incandescence” Greg Egan tells two stories, apparently disconnected and in totally different situations.

In “Rollback” Dr. Sarah Halifax is the scientist who in 2010 manages to decipher an alien message arrived from the Sigma Draconis system and gives her contribution to create an answer that is sent to the aliens, who unfortunately live almost nineteen light years from Earth.
