The Fall of Sunset Shimmer

Princess Celestia's best student, Sunset Shimmer loves to read books. She thinks of friends as a waste of time. She tells Celestia exactly that when the Princess Of The Sun tells her to make some friends. One day, Sunset meets a grey-furred, black-maned stallion. They become best friends after they first met. When Sunset tells Celestia about her new best friend, Celestia finds out more about that stallion. She warns Sunset not to be his friend, but Sunset doesn't listen. When the time comes, who shall she be loyal to? Her friend, or her teacher? Time shall tell.
