On Annabeth's fourteenth birthday, two weeks before she has to move to San Francisco for a year, Percy gives her a bunch of "Open This When" letters, as a way to remember him. A Mortal AU, and a bit OOC. There's a reason why Humour isn't a genre. (I'm not funny.) Rated T just in case. Nothing M.

When Percy is babysitting Annabeth's daughter, he has to tell her a story in order to make her fall asleep. Is the story Percy tells her true? Well, read to find out.
