Since the age of twelve, Beomaris has been haunted by the same dream—of a mysterious girl cloaked in moonlight. He doesn’t know her name, only that his soul reaches for her.

Now temporarily crowned as king, Beomaris makes a bold move: opening the royal army to women, a gesture meant to honor them—until fate places her right before him. The girl from his dreams is real… and she's a soldier in his ranks.

But while destiny begins to stir, so do secrets within the castle walls. Because the king has his own plans. And fate is never quiet for long.
