A desperate family confronts the mysteries that lie between life and death in this soul-gripping novel of supernatural suspense by Amazon Charts and New York Times bestselling author Christopher Rice.

Claire Huntley and her brother, Poe, were on a midnight hike in Montana when the woods went wild. A blinding, devouring light and a rumbling pulse that blasted them off their feet left both kids with little memory of what happened. Their father insisted it was a violent extraterrestrial abduction; his wild obsession would tear their family apart in the wake of the trauma.

Fourteen years later, Claire, who's battled anxiety attacks since that fateful hike, wants to heal her relationship with her brother, which has been damaged by his years of addiction. But only hours before their reunion, Poe's crowded passenger plane plunges into the Colorado mountains. No one survives the fiery crash. In the midst of her grief, Claire accepts her estranged father's request to join him in Montana, where he continues to investigate the paranormal force he believes altered his children down to their bones.

As they reunite, Claire's anxiety attacks take on a new dimension. Is she experiencing hallucinations or visions? Is her brother's presence in them a symptom of grief, or is she receiving messages from beyond life? The answers Claire and her father seek will take them on a breakneck journey deep into the Montana wilderness and the shadows of history, where they will unearth a secret force with terrifying implications for their family--and the world.
