She thought she left her darkest nightmare worlds away in the Australian outback. Now, terror will push her to the edge....

Shut down by the grief of losing the man she loved, Tally Nowata has come home to pursue the search-and-rescue work that is her passion. When a crank phone call leads Tally and a friend to the top of a treacherous peak, it is the start of a violent game that will force Tally not only to the heights of danger in Wyoming's Grand Tetons, but to the brink of sanity in a race to the death. A lethal predator is closing in on Tally. He's dead set on revenge -- and he's targeted the one thing Tally can't survive without: her child.

Hannah Nyala, the real-life tracker who introduced Tally Nowata in the electrifying novel Leave No Trace, brilliantly defines a woman's determination to embrace life after her spirit is shattered -- and crafts a nail-biting chase across a hazardous landscape, where no one can rescue the rescuer.
