She was a forgotten girl, a runaway found murdered on the High Line train through the northern Rocky Mountains and, with little local interest, put into a dead file. Only, she was not alone. When Kirk Stevens and Carla Windermere stumble upon the case, they discover a horror far greater than anyone expected - a string of murders on the High Line, all of them young women drifters whom no one would notice. Through the bleak midwinter and a frontier land of forbidding geography, Stevens and Windermere follow a frustratingly light trail of clues - and where it ends, even they will be shocked.
