Diamond Dust - Tanner Park

IN THE 22ND CENTURY, a breakthrough discovery during a multinational crewed mission to Jupiter's moon of Callisto revolutionizes both industry and warfare behind the scenes.

Enter a world of high-tech lust. Years later, a hydrogeological survey beneath the retreating glaciers of Greenland uncovers a model of the human form near the edge of evolution's passage. An engineered slave soldier purpose-built for a remorseless advanced civilization of the ancient Solar System, created to serve a vile, technocratic precursor race of humans. For a living monument to a dark future from the past, adapting to the technological milieu of Earth in 2187, even at its worst, comes naturally.

He encounters a secretive organization of eco-conservationists from the colonies of Mars, who've learned of his time and origins during their expeditions to Jupiter and hope to prevent a final conflict fueled by the circumstances that razed his worlds. Enamored by Earth's auroral beauty and culture, he finds something to lose.
