Now, as enemies gather at his weakened borders, the young king must find a way to refill Ravka's coffers, forge new alliances, and stop a rising threat to the once-great Grisha Army. Yet with every day a dark magic within him grows stronger, threatening to destroy all he has built. With the help of a young monk and a legendary Grisha Squaller, Nikolai will journey to the places in Ravka where the deepest magic survives to vanquish the terrible legacy inside him"--Amazon.
