Cassidy Ivanoff and her father, John, work at the new and prestigious Curry Hotel outside Mt. McKinley. While John will be an expedition and wilderness exploration guide for the wealthy tourists, Cassidy has signed on as a cook's assistant. Both are busy as the hotel prepares to welcome the president of the United States on his way to drive in the golden spike to officially complete the railroad.
Allan Brennan travels to the Curry Hotel to be an apprentice of a seasoned Alaska mountain guide. Ever since his father's death climbing Mt. McKinley, he's worked to earn enough money to make the trek to the Alaska territory himself. His father's partner blames their guide for the death of his father, but Allan wants to find the truth for himself. He finds an unlikely ally in Cassidy, and as the two begin to look into the mystery, they suddenly find that things are much less clear, and much more dangerous, than either could ever imagine.
