Queen's Trial begins, and the competition turns deadly fast. There's danger behind every turn, and it's not just the competition that wants Cassia dead. To make matters worse, Tristan, the Winter Prince, has a plan of his own. He takes Cassia to the Winter Court where she'll have to compete without the Princes she's come to depend on. Will things stay ice-cold in the Winter Court or will she succumb to the steamy bad boy Prince with his own agenda? Things aren't always what they seem, though. Cassia might have the magic to become Queen, and the love of her Princes. But with that target on her back, will she survive to get the chance?
