For a thousand years, Concordia has maintained peace between its provinces. To mark this honorary feat, the emperor's ship embarks upon a twelve-day voyage to the sacred Goddess's Mountain. Aboard are the twelve heirs to the provinces of Concordia, each graced with a unique and secret magical ability known as a blessing. All except one: Ganymedes Piscero ? class clown, slacker, and all-round disappointment. When a beloved heir is murdered, everyone is a suspect. Stuck at sea and surrounded by powerful people, odds of survival are slim. But as the bodies pile higher, Ganymedes must become the hero he was not born to be. Can he unmask the killer and their secret blessing before this bloody crusade reaches the shores of Concordia?
