Some betrayals cut deeper than blades. The Blades were never supposed to survive this long. But after the battle in Quu Harbor, escaping is no longer enough. The most dangerous liars in the four realms have one last mission - return to Yusan and finish what they started. But now a usurper sits on the serpent throne. And he may be more dangerous than the god-king. With three relics of the Dragon Lord in their possession, the Blades will face the might of the four realms. Enemies will become allies. Allies will become traitors. And the ones they love most? They'll be the ones to break them. Grief will carve the Blades into something ruthless and unrecognizable. But only by losing everything can they win this game of kings and crowns.
