Olivia Taylor-Jones has everything a beautiful young socialite could want. Her well-to-do family, though clouded by the early death of her father, affords her endless luxury and comfort. Her charming fiancé has his own swimming pool full of money and growing political aspirations to match. Her profession is light enough to not be intrusive, but charitable enough to make her look like a shining example of womanhood. She’s also bored and aimless, which means it’s the perfect time for something unexpectedly awful to happen. In her case, she and the rest of the tabloid-obsessed world discover her real parents are infamous serial killers Pamela and Todd Larsen, and that her adoptive parents were awarded custody after her birth parents were arrested.
To rub salt in her wounds, her adoptive mother flees to Europe to cope with the revelations, an act Olivia—aka Eden Larsen—interprets as abandonment. When the man she loves pushes her away to protect his upcoming campaign, she cuts all ties and goes into hiding, albeit poorly. Several life-threatening experiences later, Olivia winds up in Cainsville, Illinois, a small town in the middle of nowhere practically dripping with dark secrets. Nothing in the township is what it seems, and everyone knows more than they should about things that go bump in the night.
