In 1895, less than two years before the publication of `Dracula' Bram Stoker wrote this now forgotten novella about a romance set against the background of the mountains in the West Coast, USA.

The name of the book refers to Mount Shasta, located in northern California. Rich English heiress Esse is told by her doctor that she should spend the coming summer on this high mountainside to recover her health, and is sent to the cottage with her mother. Esse, after some adventures including the fight with wild bears, falls for Grizzly Dick, American guide and bear-hunter.
