Proxima Dying: Proxima, Book 2 (Unabridged‪)‬

An intelligent robot and two young people explore Proxima Centauri b, the planet orbiting our nearest star, Proxima Centauri. Their ideas about the mission quickly prove grossly naive as they venture about on this planet of extremes.

Where are the senders of the call for help that lured them here? They find no one and no traces on the daylight side, so they place their hopes upon an expedition into the eternal ice on Proxima b's dark side. They not only face everlasting night, the team encounters grave dangers. A fateful decision will change the planet forever.
