Double threat
(Book)

"A Tom Doherty Associates book."

"Double Threat is a new stand-alone thriller from New York Times bestselling author F. Paul Wilson. Daley has a problem. Her 26-year life so far has been unconventional, to say the least, but now she's got this voice in her head. It claims to be a separate entity that's going to be sharing her body from now on. At first she thinks she's gone schizophrenic, then considers the possibility that maybe she really has been invaded - but by what? Medical tests turn up nothing, yet the voice persists... and won't stop talking! When she finally accepts the reality that she has a symbiont, she discovers that together they can cure people of the incurable. Maybe hosting a symbiont isn't such a bad thing. She retreats to a remote town in the southwest desert to hone her healing skills. But there she runs afoul of the Pendry clan, leaders of an obscure cult that worships the Visitors who inhabited the area millions of years ago. They plan to bring them back but believe Daley is the prophesied "Duad" who will undo all the cult's efforts. She must be eliminated. You know things are bad when the voice in your head is the only one you can trust"--
