The Unexpected Heroes

(Starts partway through The Mark of Athena, before the aquarium, battery, etc. I use a little of the plot from there on, but not much.) On board the Argo II, a storm hits and ruins the ship, but not to the point where Leo will give up. Piper sees that Percy has been hiding a secret, Frank and Hazel know they need to get to Nico before it's too late, but they don't have a way to get to Rome in order to save their friend, and Hazel's brother. Annabeth goes on a solo quest, to find what her mother sent her to do. Will each be able to complete their respective tasks, and the one they set out to accomplish as a whole? Maybe Rachel doesn't see the prophecy happening then, maybe it's set for the future. Maybe, they're being pulled apart from the inside.
