Forbidden Love's Trap (Dramione AU)

Shortly after Hermione was born, she disappeared from her muggle home only to be found by Lucius Malfoy with only a blanket embroidered with her first name to identify her. Realizing that she's a witch, he and his wife adopt her, raising her as a pureblood. She is sorted into Slytherin, but that doesn't stop her befriending Harry and Ron. Because she and Draco are raised as siblings they're very close, but as they get older Draco's feelings for her begin to change and he thinks he must be losing his mind. Little does he know that Hermione feels the same way.
Everything changes when the school announces that they're going to hold a Halloween masked ball during their sixth year in order to try and promote friendship between the houses. What will happen during the dance? How will they react at the end of the dance when everyone is unmasked? Will they deny what happened or will they fall into the trap of forbidden love? What will they do when they are confronted with truth of Hermione's origins?

A/N: The Dark Lord doesn't exist in this universe, the Malfoys aren't evil, Neville's parents are sane and Harry's parents are still alive.
