Teenager Henric is surprised to learn his father is the exiled king of a fantastical world of eternal winter. He and his kin are now being called back to defend the kingdom from their enemy, a rival family with a centuries-long grudge. As Henric adjusts to his new position and growing power, he must decide what kind of ruler he will be: one who wages war or one who attempts peace.

Featuring a bisexual male protagonist, this new-adult fantasy blends the wonder of the Chronicles of Narnia with the political intrigue of The Crown and the epic scale of House of the Dragon.
