MYSTERY AT CHILKOOT PASS is the 17th book in the "History Mystery" series. It is autumn, 1897, and twelve-year-old Hetty, her friend Alma, their parents, and Hetty's Uncle Donall have left their homes in San Francisco to seek gold in the Klondike gold rush. They must get themselves and three tons of supplies and equipment up and over Chilkoot Pass before winter sets in. Thousands of other goldhunters are making the same trek. The story follows their struggle from the time they leave their ship near the coastal town of Dyea until they ascend the Pass. Along the way, large amounts of cash and small personal items of little value disappear. Hetty suspects her uncle might be a thief. Thieves are dealt with harshly in this frontier environment. Hetty proves to be a person of strength and resolution. She works hard and does what she has to in the face of hardship and death. MYSTERY AT CHILKOOT PASS is a worthy addition to the "History Mystery" series. It will make you appreciate the hardships people were prepared to endure in the pursuit of fortune. It may also make you wonder what could have possessed people to leave their homes and put themselves through such hardships on the slim chance that they might find enough gold to make themselves rich. A nice introduction to an interesting bit of history.
