Percy Jackson's Lost Twin

She gave birth to 2 wonderful twins. One boy and one girl. Their names were Perseus and Emma Jackson, born on August 18, 1993. Sally Jackson couldn't have been more happy. Poseidon was a bit worry because of the pact he and his brothers made, but, who cares. Once out of the hospital,Sally Jackson carried her 2 newborn babies to her small apartment. That night, one terrible thing happened. 3 cyclops entered through the window and took away Emma. Sally was devastated. She searched and and put up flyers but nothing happened.

12 years later, Sally saw her little Percy grow up. He was tall and handsome and she was very happy that he was still with her. Sally never told Percy about his sister,Emma, for 2 reasons. One, she didn't want to remember what happened that night at August 18, 1993. And two, she didn't want Percy to be upset about his sister. One thing Sally did knew, was that her little Emma was still alive, somewhere, and hopefully safe.
