In the sprawling desert city of the Nine Star Region, Earthman Ryn Barlow hunts a vanished scientist whose experiments tore open a doorway between worlds. What begins as a search becomes a race against an alien conspiracy spanning centuries—hidden portals buried beneath ancient ruins, and enemies who can step across light-years in a heartbeat. Guided by a mysterious woman with silver eyes and pursued by agents of the Terran Trade City, Barlow must unlock the secret of the Doors before they fall into the wrong hands. But some doors, once opened, can never be closed again.
