Marc Milner, a history professor at the University of New Brunswick who has written non-fiction about the Canadian navy, also stays in familiar waters with Incident at North Point (Vanwell Publishing, 234 pages, $24.95 cloth). The novel is based on the sinking of a German submarine off Prince Edward Island in May 1943-an event that is a local legend but that has never been officially confirmed. It also presents a fragment of an era, including the Canadian political climate of the time, and is most likely to appeal to readers who have an interest in World War II and in Canadian naval history, in particular.
