As a distraction, she takes on a new case involving a fifty-year-old, mummified corpse discovered in a hidden enclave at High Lonesome, a long-abandoned New Mexico ghost town. Quickly out of her depth, she realizes she needs the help of her old enemy, archaeologist Nora Kelly.

Or will they - like others before them - die in the attempt?

New York Times bestselling authors Preston & Child return with their new thriller featuring fan favourites Nora Kelly and Corrie Swanson. When a billionaire invites her to lead his excavation of the infamous Roswell landing site, Nora Kelly, now jobless, reluctantly agrees to visit. When preliminary scans of the area reveal a suspected Native American burial site, Nora takes a closer look. But this is no indigenous burial site. It's a crime scene. Nora uncovers two dead bodies, one with a bullet hole in its skull. Dead bodies mean this is a case for the FBI, and Nora knows just the person to investigate: Special Agent Corrie Swanson. As Corrie and Nora dig deeper into the mystery, they will uncover more questions than answers. And the truth they seek will be even stranger than the conspiracy it hides behind...
