Who is Catalia Fisa? With the help of pivotal figures from her past, Cat begins to understand the root of her exceptional magic, her fated union with Griffin Sinta, and Griffin's role in shaping her destiny. Only Cat holds the key to unlocking her own power, and that means finally accepting herself, her past, and her future in order to protect her loved ones, confront her murderous mother, and taking a final, terrifying step - reuniting all three realms and taking her place as the Queen of Thalyria. What doesn't kill her will only make her stronger . . . we hope.
