On Edge is a romantic mystery thriller. The book is slow at the start, and it took time for me to visualize Emanuella and begin to understand her. Emanuella's friend Surge was, by far, my favorite character and seemed like the best friend I've always wanted. The mystery is perhaps the strongest aspect of the novel, and the intricate descriptions pull the reader into the story. I was shocked when the killer was revealed. One thing that I learned from reading this novel is to trust my gut instincts. I recommend this novel to readers above age 13 who enjoy romance and mystery.
