King of Scars

The boy king. The war hero. The prince with a demon curled inside his heart. Nikolai Lantsov has always had a gift for the impossible. Yet with each day, a dark magic within him grows stronger, threatening to destroy all he has built. His country is Nikolai's first love, and whatever it demands, he will give. Zoya Nazyalensky has devoted her life to honing her deadly talents and rebuilding the Grisha army.
Despite their magical gifts, Zoya knows the Grisha cannot survive without Rakva -and Ravka cannot survive a weakened king. Zoya will stop at nothing to help Nikolai secure the throne, but she also has new enemies to conquer in the battle to come. Far north, Nina Zenik wages her own kind of war against the people who would see the Grisha wiped from the earth forever. Burdened by grief and a terrifying power, Nina must face the pain of her past if she has any hope of defeating the dangers that await her on the ice.
Ravka's king. Ravka's general. Ravka's spy. They will journey past the boundaries of science and superstition, of magic and faith, and risk everything to save a broken nation. But some secrets aren't meant to stay buried, and some wounds aren't meant to heal.
