Andrew and his fiancee, Hannah, are on board a whale-watching boat in the Bay of Fundy when the vessel is hit by a rogue wave. Thirty-eight people are rescued by the coast guard, but Hannah is not one of them, and she is subsequently presumed to have drowned. Some weeks later, however, a friend sends Andrew a link to a wedding video shot in southern Mexico, and who is there but Hannah, sitting next to a man her friends do not recognize. Desperate to get to the truth and find his fiancee, Andrew hires a detective, Matthew Harding, whose search takes him from New Brunswick to Mexico to the United Kingdom and finally to the caves under Peterborough, Ontario. A fast-paced thriller full of colourful characters and supernatural elements. The Rogue Wave hits the reader broadside.
