For years, Gansey has been on a quest to find a lost king. One by one, he's drawn others into his mission: Ronan, who steals from dreams; Adam, whose life is no longer his own; Noah, whose life is no longer a life; and Blue, who loves Gansey … and is certain she is destined to kill him. *Nothing dead can be trusted.* *Now the endgame has begun.* *Nothing living is safe.* Dreams and nightmares are converging. Love and loss are inseparable. And the quest refuses to be pinned to a path.
