HP 2: Secrets with Serpents

CoS: Harry, Ron, Hermione, and Ezra return to Hogwarts for their 2nd year. What happens when impending messages appear on castle walls, students are attacked and stiffen out of nowhere, and a diary that seems to be the center of this mystery, all suspiciously pointing to Harry? Also all things related to "Harry Potter" belong to J.K. Rowling (amazing woman!); OCs in here are mine.
