They are all excited to welcome a new wondercolt to their school. Sunset and Pinkie Pie are the ones who decide to greet the new student. Upon meeting the student, whose name is Twilight Sparkle, Sunset realizes she has developed a crush on her. But being a vampire means that she could pose a danger to Twilight. She struggles to keep her vampiric nature a secret. But when an old enemy from Starlight's past comes into town, she realizes they are in danger. She and Starlight must keep their much stronger, much older enemy out of town. If they don't they could risk revealing their secret to all of Canterlot, if not all of Equestria.
