It begins deep in the woods of the Pacific Northwest, at the site of a reported shoot-out. Investigator Colin Cellars cannot find a trace of perpetrator or victim�or even confirm that anyone has been killed. As he doggedly pursues the case, he realizes there is far more at stake here than murder. Someone�or something�will stop at nothing to prevent him from discovering the truth. For the truth is not "out there;" it is locked away in Cellars' own evidence file. And the evidence points to a killer far outside Cellars' experience�far outside any earthly experience. But who will believe one maverick cop?

From the New York Times bestselling author of Balefire comes a chilling tale of murder, forensic detection, and vivid speculation that pits a unique crime scene investigator against a culprit who may be unlike any this world ever spawned.
