But appearances—and rivals for the throne—can be deceiving. When Eden’s king and crown prince are killed by assassins, Eden desperately needs a monarch, but the line of succession is no longer clear. With a ruling council scheming to gain power, Carys and Andreus are faced with only one option—to take part in a Trial of Succession that will determine which one of them is worthy of the crown.

As sister and brother, Carys and Andreus have always kept each other safe—from their secrets, from the court, and from the monsters lurking in the mountains. But the Trial of Succession will test the bonds of trust and family. How long before suspicion takes hold and the thirst for power leads to betrayal?

With their country and their hearts divided, Carys and Andreus will discover exactly what each will do to win the crown.
