Inverted Frontier Series

Deception Well is a world on the edge, home to an isolated remnant surviving at the farthest reach of human expansion. All across the frontier, other worlds have succumbed to the relentless attacks of robotic alien warships, while hundreds of light years away, the core of human civilization - those star systems closest to Earth, known as the Hallowed Vasties - have all fallen to ruins. Powerful telescopes can see only dust and debris where once there were orbital mega-structures so huge they eclipsed the light of their parent stars

Urban is no longer master of the fearsome starship Dragon. Driven out by the hostile, godlike entity, Lezuri, he has taken refuge aboard the most distant vessel in his outrider fleet. Though Lezuri remains formidable, he is a broken god, commanding only a fragment of the knowledge that once was his. He is desperate to return home to the ring-shaped artificial world he created at the height of his power, where he can recover the memory of forgotten technologies. 

"Tanjiri is not for you. You are not ready to encounter what exists there." So Lezuri spoke in warning, long ago. Urban still possesses the strange gift—the impossible puzzle—Lezuri gave him that day. A needle, ultra-thin and twelve centimeters long, with a silvery surface that slices light into rainbow glints. All Lezuri's knowledge lies locked within that needle. Urban has only to discover the trick of opening it, to gain that knowledge for himself—but the needle remains an enigma.
