It's been eight years since the Titan War, and all had been peaceful. Until Killian is found missing one day. A trip to the Grand Canyon reveals a plot that even Michael and Percy are hesitant to share. And we finally meet a certain daughter of Athena. I do not own many of the characters. Rights to the story and most of the characters belong to Rick Riordan. I own the characters of Michael, Aelin, Killian, and Lilly.
