The Haunted Horn is surely a novel that will appeal to younger readers and likely make history, (perhaps for the first time in their lives!) interesting. By coupling it with mystery, paranormal and historical events, Willett constructs a story that is anything but boring. Any age reader will find it enjoyable, but it is geared towards the early middle-school reader based on language and subject matter. The Haunted Horn teeters on also being described as a coming-of-age story because it incorporates issues of bullying, parental relationships and girls, all that are faced by the male main character, Alex. Although, somewhat resolved, these problems are not the singular focus of the plot. Fans of shows like The Haunted Collector and Warehouse 13 will likely love this book. Attachment to objects is an interesting subtopic of paranormal investigation. This story not only explores the historical Civil War, but ties it into the modern curiosity of haunted objects. When the past collides with the present, what strange things can occur!
