The disappearance of a mysterious informant leads two people desperate for answers to an island of deadly deception in this new novel in the Lost Night Files trilogy by New York Times bestselling author Jayne Ann Krentz.

Talia March, Pallas Llewellyn, and Amelia Rivers, bonded by a night none of them can remember, are dedicated to uncovering the mystery of what really happened to them months ago--an experience that amplified innate psychic abilities in each of them. The women suspect they were test subjects years earlier, and that there are more people like them--all they have to do is find the list of others who took that same test. When Talia follows up on a lead from Phoebe, a fan of the trio's podcast, she discovers that the informant has vanished.

It's clear he has his own agenda, and they are instantly suspicious of each other. But when a killer begins to stalk them, they realize they have to join forces to find Phoebe and the list.

It soon becomes clear that Phoebe is not the first person to disappear into the strange gardens that surround the Unplugged Experience retreat. And then the first mysterious death occurs. ...
