In the first volume of the Westcoast Series, Westcoast Legacy, Margaret Manson uproots her family from an established life in Greenock, Scotland and strikes out on a risky future as indentured colonists for the Hudson's Bay Company at Fort Victoria on Vancouver's Island. In keeping with the author's claim that most of the information in these stories is true, the prequel section of the story goes back in history yet another hundred and fifty years to describe some background, both historic and scientific, to establish meaning and understanding of many of the subjects covered. The main part of Westcoast Bounty (the sequel), picks up the story several generations later, as Margaret's great grandson, Jack Manson, becomes intrigued when some of the unresolved mysteries of Margaret's adventures surface, creating even more dangers and potential rewards for those involved. On a construction site in modern day Victoria, workers uncover an old journal and discover it belonged to Jack's great grandfather, Margaret's husband, who was washed overboard and lost on his way to Victoria. Jack rallies his friends and colleagues to help solve the unknowns, especially the reference to Spanish gold in the journal. They work together to decipher the journal and solve a generations-old family riddle from Jack's family. As they try to solve these puzzles, the subject of Spanish gold creates serious interest and complications from others with powerful gang connections as far as Vancouver and Hong Kong. So again, they are thrown together into a complicated web of confusion, deceit and danger as they try to solve the mysteries of Margaret Manson's great westcoast adventure.
