(All rights to L.J. Smith and VD producers) Zara Rose has been numb since her parents' car crash and her move to Mystic Falls with her younger brother Preston. Her uncle Ashton, her legal guardian, has never been more worried. Soon she meets Elena Gilbert, an girl with an amazing resemblance to her. Elena's boyfriend, Stefan, and his brother, Damon, are very suspicious. She acts much like Elena, and looks like they could be sisters. When Katherine returns to town, suspicions are drawn. She now has two boys desperate for her love, but she will only choose one. Her looks are uncanny, but not enough to be a doppelgänger. So what is this girl's secret?

What if Elena had a twin sister Karin who acted similar to Katherine but is a vampire hunter? What happens when they meet the Salvatore brothers for the first time and fall in love without knowing about Katherine and vampires? What if Damon only wanted Karin because she's exactly like Katherin? Will they fall in love for real or just for fun? Her name is Karin Gilbert the other doppleganger.
