High altitude climbing is difficult enough without supernatural creatures thrown into the mix. Unfortunately for Greg and Quinn, they may have stumbled into just such a situation. A few days into their week-long trek, they begin noticing strange occurrences. Voices outside their tent, a mysterious hiker off in the distance, and a predator that might be the end of them.

When they don’t arrive home as expected, Greg’s godmother, Ellie Jensen, starts to worry. A search and rescue veteran with years of expertise in the Southern Picket Mountain Range, she sets off in pursuit of the young mountaineers.

Five hundred feet above safety and one thousand feet below it, can two young climbers manage survive long enough for help to arrive, or will they become yet more mysterious disappearances on the high mountain peaks?
