In Dingus’ SF novel, a ruthless company that controls Earth risks war with an alliance of outer-planet colonies over control of an alien sphere. 

The author sets this space-faring tale in the year 2240, well after Earth has been taken over by the amoral, profit-driven mega-capitalists who ruined it. A Saturn Commonwealth of human colonies in deep space maintain a free democracy. Miner Serena Roe works on Commonwealth territory; she was once a forced-conscript in the hated company’s military wing, and her body still carries advanced cybernetics, which were supposedly deactivated after she received a discharge for refusing to commit atrocities against Mars labor-union rebels. Serena is still employed by the same company, and on duty belowground on Saturn’s largest moon, Titan, when she witnesses a deliberate explosion and survives an assassination attempt. It turns out that a ruthless company executive has learned of “the artifact”—an uncanny, physics-defying alien sphere under Titan’s surface. Intending to weaponize the object’s technology, the company sends warships to seize the Commonwealth land, as the artifact itself seems immovable. Meanwhile, Serena finds herself drawn to the sphere, as her supposedly offline implants curiously respond to it—and she hasn’t forgotten that “Somebody wants me dead, me in particular.” Dingus includes many familiar ingredients in this first-contact SF scenario; the sphere, for instance, calls to mind Arthur C. Clarke’s “monolith” in 2001: A Space Odyssey (1968). However, this story becomes more of a military-intrigue thriller as murderous forces of the company go up against the outgunned but resourceful fleet of the Commonwealth—space-born folk who, à la Robert A. Heinlein’s work, have become a wiser culture than the materialist bullies back on Earth. Their conflict provides nail-biting moments, almost elbowing aside content about the wondrous alien whatsit and its purpose, which may remind readers of Carl Sagan’s Contact (1985). Like Sagan and Clarke, Dingus is a scientist, and he brings a sense of verisimilitude to the unearthly epic without overwhelming the narrative with technological jargon; he also conjures a tough, sympathetic main character. 

A savvy, mind-expanding outer-space tale that imbues a familiar premise with suspense.
