Notes or Letters. They're too Similar

Elodie Monroe, a red-headed and gorgeous, yet outspoken teenage girl experiences something that usually only happens in the books. She receives a love letter, some might call it a love note, in the first week of starting her new school, Westview. She wasn't sure whether to be appreciative that someone liked her or to be creeped out that someone liked her this early. She has no idea who it could be since there's thousands of students at Westview, but her new friend, Emily Bennett, is like a detective you only see in those high school dramas. She's dedicated to finding out who wrote the note, letter as Elodie calls it. It gets even harder to figure out who it is when more letters keep showing up, the body of the letter(note) is in different handwriting every time, but always signed the exact same. Who could it be, and why does Elodie have a hunch someone's perhaps stalking her?
