Well-written and researched involving delightful descriptions surrounding the World's Fair held in Chicago in the late 1800s with a lovely cover. This novel takes you right back to that era with a detailed description of the lay-out and offerings of the fair, making you feel a part of it. This involves a recent widow (Annie) who escorted her late husband's brilliant but absentminded older partner (Silas) to display their new invention - a horseless carriage. In their travels, Nick, Silas' nephew, who is part of a wild west show nearby assists them. Somehow through a bumbling mix-up, Silas acquires information from an anarchist who plans to assassinate the Spanish princess. This results in danger, unknowingly to them, as they attempt to procure financial production support for their invention. Annie, who assisted her husband when alive, only wanted to follow-through on his final wish, not expecting to fall for handsome Nick. Much adventure, mystery, and ultimately romance will provide a reader with an entertaining read for those who enjoy a historical genre.
