What do you do when a sociopath loves you?

Calling Laurel Snow's relationship with her newly discovered half-sister challenging is an understatement. Not only does Laurel suspect Abigail is behind the disappearance of their father, but her erratic behavior makes life in Laurel's small hometown interesting, to say the least.
