The Last Machine in the Solar System — Isaac Matthew Sobin

Nearly three billion years into the future, the solar system is a very different place. Earth is long gone, and the sun is a gray, shrunken dwarf. All that remains of humanity and conscious thought is Jonathan―the last machine.

Created to survive Earth's destruction by our ever-expanding sun, Jonathan witnessed the end of life on Earth. This is his story and that of his creator, Nikolai. It is also the story of the human race, which failed to disentangle its destiny from the star that gave rise to all life-forms on Earth.
