Rohin, Rala, Lazzir, and Crayfish are a team of Copperhawk mercenaries lost within a disjointed, terrifying labyrinth of seemingly infinite doorways. Their Guild's Psion, Valikarn Onyxsea, must use his ability of Object Reading to discover what happened to his people, where they are, and what he can do to bring them home. Even if his dogged search threatens his very sanity.
Meanwhile, an ancient presence lurks within the disparate realm the Copperhawks traverse, hunting them ceaselessly and forcing them ever closer to the center of its deadly maze.
Will the Copperhawks escape in time, or will they be drawn into oblivion by the beatific horror of Obscuria's Lure?
