Author Mark Finnan displays his talent at research and love of history, both of which make this book an excellent reference for anyone interested in the mystery of Oak Island. Finnan is a fine writer, and adds a nice human-interest angle in which he details some of the lives of those who have sought the treasure. The first few chapters provide a detailed history in the early colonization of Nova Scotia and the area surrounding Oak Island. However, most of the book provides well written detail of step by step efforts at recovering the treasure, engineering accomplishments, and both geological and archaeological findings on the island, all while telling the story of those who have sacrificed everything to find it in the last 200 years. The book includes some photos, sketches, and excerpts from early accounts and records of the search. The only criticism I have is Finnan's frequent references to the Freemason's involvement throughout the book, culminating in the last few chapters which are devoted to Finnan's own ludicrous theory of what is at the bottom of the treasure Pit. Other than that, it's an excellent guide to anyone wanting the scoop on Oak Island.
