Cordelia and her brother are mer-people. No, not Sirens. Those are two completely different beings and will make them pissed if you confuse them with one another. Moving into Beacon Hills along with their father was a lot more interesting than they thought it would be. They find a pack filled with different supernaturals, but this isn't your normal pack. It's a bunch of teenagers in high school. Cori and Josh want to get through the rest of the school year without any commotion. Of course, that's not possible when being a supernatural teenager who deals with normal life and fights off evil supernaturals who are set on killing people and power.
