Mary Paterson was a girl from England who ran away from her family to go to America in 1751. She was 15 when she was murdered on the boat, 'Lucy Oceans'. Sharon Golden is a 15 year old sophomore who just moved from San Francisco, California to Richmond, Virginia with her mother and brother. The unlikely coincidence of being in the same house causes these two very different girls meet and befriend each other, but as the two become closer, Sharon learns things about Mary that can endanger them both as Sharon tries to hide Mary's true identity from those around her. But hiding a ghost from ghost hunters isn't the smartest thing to do, especially if it might get you killed.
