Yn is new at Camp Half-Blood, but she’s already breaking rules… and reality. Clocks stop, monsters appear, and the Oracle delivers a prophecy that claims the world could be lost by her hands. Percy Jackson is assigned to watch her, protect her, and somehow survive her sarcasm—and maybe fall for her in the process. Now Yn must navigate camp life, dangerous quests, and a choice that could change Olympus forever. Funny, chaotic, and full of unexpected romance, nothing at camp will ever be the same.
