When her older, carefree sister, Eustace - a cannabis grower in Boulder, calls to inform her the great aunt they never met has died and they must travel to a small town in Connecticut to deal with the estate, she sees an opportunity to unload the house and save herself. But once there, the sisters learn they are getting much more than they bargained for. The Victorian mansion they stand to inherit is bound in a dynasty trust controlled by their late aunt's aging attorney who insists they inhabit the house and retain it but keeps them in the dark about the peculiar rituals of their ancestors. Not to mention a sexy, tattooed groundskeeper with a shrouded past who refuses to leave the carriage house and a crypt full of dead relatives looming at the property line. As both women grapple with their current predicament, they come face to face with a haunting family secret, the truth of what happened to their mother, and the enemy that's been stalking them from the shadows for generations. In a twisting torrent of terror and blood, the sisters must uncover the power within them to heal their fractured relationship, reverse their mysteriously declining health, and claim the lineage they wanted to escape but now must embrace if they are to survive at Bone Hill.
