Two unlikely allies search for the secrets of their pasts while on the run within the Alien world of Harmony in the thrilling new novel by New York Times bestselling author Jayne Castle.

Leona Griffin is at the height of her career as a para-archeologist thanks to a recent Underworld discovery. Her high profile attracts the attention of an organization of elite, secretive collectors. They want her to authenticate the artifacts that aspiring submit as evidence to their group. The ceremony takes place at a glittering reception where Leona is shocked to discover that one of the relics is a powerful Old-World object known as Pandora's Box. But she's not the only one interested in that artifact.

Oliver Rancourt, a man with a unique talent—they say you never see him coming—is also there. Leona knows she must not underestimate him. Attempting to make a discreet exit, she stumbles over the body of a waiter wearing the emblem of a dangerous cult. Before she can alert authorities, a police raid sends the reception into chaos. To avoid being arrested, Leona slips away with Oliver—a risky decision that gets her fired.

Now forced to work together, Leona and Oliver pursue an investigation that leads them to the town of Lost Creek where the locals are obsessed with a chilling legend involving a long-dead cult leader and illicit paranormal experiments. But Leona knows the real danger may be the irresistible attraction between herself and Oliver.
