Kirkus Reviews stated: "Kat's third shakes up her love life and offers a twisty mystery with enough suspects to keep you guessing to the bitter end." Publishers Weekly called the novel "satisfying" and opined that Ritter "smoothly blends history and mystery, tragedy and near-tragedy". Teresa L. Jacobsen of the Library Journal stated: " Ritter's thriller series is just right for those who love a story told in a 24-hour frame in which tons of improbable deeds transpire."
