One day, Percy and Annabeth are asked to join the Avengers. Loki is rising with the help of Nemisis, and only the Mighty Avengers can stop them. But when tradgady strikes, will Percy be able to stay sane? A/N Yes, before you ask, I'm insane. My mom's even told me, to my FACE, that I belong in a mental institute. And if you ask me, that's pretty sad.
