Five Broken Blades

Five dangerous people are drawn together by one mission: to take down the immortal King Joon of Yusan, a kingdom inspired by Korean history and myth, by stealing the enchanted crown that keeps him alive. There is Sora, an assassin sold to a cruel count; Aeri, a thief; Royo, her hired muscle; Prince Euyn, the king's exiled brother; and Mikail, the spymaster behind the plan.

They will have to work together to succeed, but they do not trust each other, and only one of them can take the crown. The first book in the Broken Blades series.
