The Lifeboat is the third novel in the Skidian Chronicles series. In The Lifeboat an asteroid is on a collision course with earth. It soon transpires the asteroid has been sent on its way by the Skidian first people who have uploaded themselves to a celestial version of the cloud and now define themselves as Transcendents.
The Transcendents have a plan for humanity which doesn't include an asteroid strike killing us all off.
The plot contains plenty of parallels with current world politics, including the introduction of a character based on a certain ginger haired world leader. The Lifeboat goes further in explaining our world history and continues the theme of the risk to humanity if we continue to ignore the dangerous degradation of our environment.
