From the writer of the New York Times bestselling The Testing trilogy comes a sweeping new fantasy series, perfect for fans of Victoria Aveyard and Sarah J. Maas.

Twins Carys and Andreus were never destined to rule Eden. Using their older brother next in-line to inherit the throne, the continuing future of the kingdom was secure.

But appearances-and rivals-can be deceiving. When Eden’s ruler and crown prince are wiped out by assassins, Eden desperately needs a monarch, however the line of succession is definitely no longer about Dividing Eden clear. Using a ruling council scheming to gain power, Carys and Andreus are faced with only one option-to take part in a Trial of Succession which will determine which of them is usually worthy of ruling the kingdom.

As sister and sibling, Carys and Andreus have generally kept one another safe-from their secrets, from the court, and from the monsters lurking in the mountains beyond the kingdom’s wall. But the Trial of Succession will test the bonds of trust and family members.

With their country and their hearts divided, Carys and Andreus will discover just what each can do to win the crown. How long before suspicion takes hold and the thirst for power leads to the best betrayal?
