Thirteen year old Prince Kyril and Mags and Amily's fourteen-year-old son Tory "share" the Gift of Farsight—although neither of them are Chosen. After much debate, the Herald's Collegium has decided to test and train them anyway. That's when the surprises start. They do not share a single Gift; they have two complementary Gifts working together in a way that the Heralds have never seen before. Their Gifts become crucial when Mags gets a desperate message from his cousin Bey, the head of the enigmatic assassin-tribe, the Sleepgivers. Bey's eldest daughter has been kidnapped, but he doesn't know why or by whom. He's calling in the debt Mags owes him to find his daughter before it's too late. Tory is certain that if anyone can find her, he can. But that will mean traveling out of Valdemar into an unknown, dangerous country. And it will mean taking a Royal Prince with him.
