She's Been Found

Katherine Pierce is practically the devil. But when Katherine meets a 3-year-old girl named Elena who is supposed to be her doppelganger, she slowly changes who she is... until she has to walk away from the girl she practically raised.

Call her pure evil for lusting after a girl not even half her age.
Call her many things but be aware that no one knows Elena as Katherine does.

Because soon enough, Elena will get older and have the same thoughts.
