I'm looking for an Edward and Bella time period fanfic. In the story Charlie is sending Bella away (I think for an arranged marriage). Edward is a knight/lord/duke (I forgot) who is feared by people because of his ability to fight. Charlie sends Edward to accompany Bella along the journey to her new life. At first Edward and Bella don't get along but then end up falling in love. Bella ends up pregnant. Bella's sister Alice sneaks along, who almost drowns at some point but is saved by Bella. Rosalie is in the story and has magical powers. She gives Edward and Bella pouches that contain a special message about their love and tells them not to open them until they're ready.
