Lucas Tappan, a wealthy and eccentric billionaire and founder of Icarus Space Systems, approaches the Santa Fe Archaeological Institute with a proposal for an excavation, and a hefty donation. Hoping to bring welcome publicity to the privatized space travel industry, he wants to finance a careful, scientific archaeological excavation of the 1947 Roswell Incident site. The Institute agrees and Nora, much to her annoyance, is tasked with the job. Instead of the evidence of a crashed UFO, Nora's excavation immediately uncovers two unknown murder victims buried at the site. Because it's on federal land, the FBI is called in and Agent Corrie Swanson is assigned the case. The discovery eventually opens up a pandora's box of mystery and atomic espionage, and a present-day menace that puts all their lives at grave risk.
