Conscious of the potential exile to the Margin, the vast and deadly wastes surrounding the still-recovering towns, the Circuit rarely experienced crime more serious than a drunken fistfight at the local bar. However, when a member of the Hosts of the Fallen Suns is murdered and a relic vital their order is stolen, Vera Lynde, resident maverick, steps into the role of detective to find who killed her friend. Her investigation begins to shine a light into the shadows that threaten not only the Host order, not just Hinge, but the entire Circuit.
