Rose McFarland is a trained killer-a Memphis S.W.A.T. sniper with a secret. Her team knows about the burn scars that lurk under her clothes, a legacy of the house fire that killed her father and brother sixteen years before. Her supervisors know that she spent two years in a rehabilitative facility, healing and learning to cope with the emotional trauma of the fire. But no one knows about the visions that drove her there, angry spirits that consumed her childhood, alienated her from her family and made her doubt her own sanity-the Whispers. When Charlie Akers, a half-brother she never knew, ends up on the wrong side of Rose's rifle, she unwittingly sets off a chain of events that puts her family in the middle of increasingly dangerous paranormal visitations. Charlie won't stay dead, and soon ghosts from Rose's past are creeping back into her life. People she's killed in the line of duty, family she thought long buried, every one of them under the influence of Rose's greatest fear, the Whispers themselves. As the walls between our world and the world of the dead grow thin, Rose will have to face her old nightmares to stop the Whispers from breaking free. If she can't, it won't just be Memphis that falls to the dead-there will be no safe place left on earth for the living.
