Following the death of his father, Thomas Walsh had to grow up quickly, taking on odd-jobs to keep food on the table and help pay his gravely ill mother's medical bills. When he's offered a highly paid position as an interpreter for an heiress who exclusively signs, Thomas — the hearing child of a Deaf adult — jumps at the opportunity.
But the job is not without its challenges. Thomas is expected to accompany Vivienne wherever she goes, but from the start, she seems determined to shake him. To make matters worse, her parents keep her on an extremely short leash. She is not to go anywhere without express permission. She is not to deviate from her routine.
She is, most importantly, not to be out after dark.
A selective-mute, Vivienne Farrow hasn't said a word in years — not since going missing in Red Rock Canyon when she was four years old. No one knows quite what happened to her out in the dark. They only know that the sound of her voice is now as deadly as a poison. Anyone who hears her speak suffers a horrible death.
Ever since that fatal family vacation, Vivienne has been desperately searching for a way to regain control of both her voice and her body. Because the face staring out of the mirror isn't hers. It's something with teeth.
Thankfully, Vivienne has a plan. She's finally found someone who claims to be able to perform a surgical exorcism. She just needs to find a way to get rid of Thomas first. But Thomas can't afford to walk away, nor is he willing to abandon the mysterious girl he's quickly falling for, no matter what dark powers threaten to swallow them both whole.
