The Teen Vampire Diaries 
Spencer Stilinski is the younger twin - by two minutes - of Stiles Stilinski. They were as closer as two people could be. They shared a bestfriend, had the same sarcasm, the brains, the nosiness, and more. They were so alike, most people couldn't tell them apart. It didn't matter that they were different genders; they were the same, they were one. The two were inseparable.
After another one of their mischievous schemes, their father, Noah Stilinski, was done with the twins finding trouble. He decided to send Spencer to his half sister, Jenna Sommers', place. Mystic Falls was crawling with vampires and other supernatural creatures, resulting in a lot of drama. When Spencer arrives, she runs into more trouble than some petty break in or a silly prank.
But what happens when Niklaus Mikaelson comes to town and his eyes latch onto Spencer? What if he starts to feel something for the younger Stilinski twin?
