#1 New York Times bestselling authors Preston & Child continue with the next book featuring archaeologist Nora Kelly and FBI Agent Corrie Swanson.

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 Kelly, 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 to 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.

The thrillers of Douglas Preston and Lincoln Child "stand head and shoulders above their rivals" (Publishers Weekly). Preston and Child's Relic and The Cabinet of Curiosities were chosen by readers in a National Public Radio poll as being among the one hundred greatest thrillers ever written, and Relic was made into a number‑one box office hit movie. They are coauthors of the famed Pendergast series, and their recent novels include The Scorpion’s Tail, Crooked River, Old Bones, and Verses for the Dead. In addition to his novels, Preston writes about archaeology for the New Yorker and Smithsonian magazines. Lincoln Child is a former book editor who has published five novels of his own, including the huge bestseller Deep Storm. Readers can sign up for The Pendergast File, a monthly "strangely entertaining note" from the authors, at their website, www.PrestonChild.com. The authors welcome visitors to their Facebook page, where they post regularly.
