Insomnia: A Harry Potter fanfic

Insomnia is a Draco Malfoy x OC fanfic. Courtney Sallow is a Slytherin, who is in her 6th year of Hogwarts just like one of her best friends, Draco Malfoy. She has trouble sleeping in her dorm at Hogwarts, so she spends most of her nights in the Slytherin common room, alone. She learned a spell that makes her invisible in secret, so she can read in peace and not get caught. Since she was invisible, she often caught other people sneaking out, but she never bothered with them. They were mostly just sappy couples anyway. One night, she caught Draco sneaking out and since she was curious she decided to follow him. The dirt she had on him after that night was enough to make her more interested in him, disgusted in his actions, but interested.
