Frostbound Throne: Song of Night

Vale was born in battle seven hundred years ago, and in all this time, he's never encountered an enemy that poses a real challenge. Until now.
Devi has been told terrifying tales of vengeful gods since her youth. She never thought that she would wake up in a world where she had to fight them.
They're opposites, he gets on her nerves, she is under his skin, and if they're to survive, they must join forces.
