The document outlines the planning for a young adult fiction story where two sisters, Sarah and Mia, live in the modern day. Mia goes missing, prompting the story. Key characters include the two sisters aged around 16 and their mother in her 50s. The author selects Mia and the mother as character perspectives. Inspiration comes from movies like Prisoners and The Forgotten dealing with missing children and mothers coping with loss. The genre will be young adult fiction with mystery, thriller and drama elements similar to Pretty Little Liars. Costumes and locations including the bedroom will need to be considered.
