"Set in 1915, William’s mother feels that`her son is socializing with the wrong crowd and is headed for trouble. In an attempt to turn this around, she has arranged for William to spend his summer working for an inventor, Alexander Graham Bell, on a hydrofoil boat. The boat is to assist the allies in defending coastal waters against the Germans. William expects the summer to be boring, but the few months turn out to be action-packed as he and his co-workers get involved in a frightening mystery. The reader gets a good sense of what life was like during this time as well as some insights into the historical context of Bell’s inventions."--Ministry of Education website.
