Sav saw her brother die. When his murderers escape unpunished, she wants justice, and the only way to get it is to join the Moon Guard, an elite order trained to keep the peace. She endures a crash-course in fighting alongside twenty-three other hopefuls. Only five of them will make the cut. Meanwhile, the thirteen families of the island fight to control the throne, and they are not afraid to use violence to meet their ends. In the far north, the shadowcats are gathering in force for the first time in a decade. War is coming -- it's just a question of who will start it. After learning of a conspiracy against the dying queen and her comrade, the young and charming Prince Kaeden, Sav faces an ultimate choice: love, duty ... or neither.
