Never What It Seems

After the Giant War, Percy thinks things are perfect. But Percy is a demigod, and things never stay that way. Annabeth cheats on Percy with a demigod- not just any demigod, though. The thing is, both Annabeth and this special demigod don't remember a thing. What is happening! PERCABETH NOT PERTEMIS OR PERACHEL. RATED T TO BE SAFE.
