The shot to the head didn't kill Nashville homicide lieutenant Taylor Jackson. But it will crack her psyche and take her to the very edge.

In her showdown with the murderous Pretender, a bullet taken at close range severed the connection between Taylor Jackson's thoughts and speech.

Effectively mute, there's no telling if her voice will ever come back. Trapped in silence, she is surrounded by ghosts-of the past, of friendships and trusts lost...of a lost faith in herself and her motives that night.

When Memphis Highsmythe offers Taylor his home in the Scottish Highlands to recuperate, her fianc can't refuse her excitement, no matter his distrust of the man. At first, the drafty and singularly romantic castle seems the perfect place for healing. But shortly the house itself surrounds her like a menacing presence. As Taylor's sense of isolation and vulnerability grows, so, too, does her grip on reality.

PTSD. Pills. Ghosts. Grudges.

Someone or something is coming after Taylor. But is she being haunted by the dead...or hunted by the living?
