Life after her high school graduation sucks for Mads Bland-her foster mother has died, her boyfriend has broken up with her, she can't afford community college, and it seems she'll work in a grocery store forever. After a mysterious invitation to Usher House arrives at her door, everything changes. Mads soon learns that her real name is Madeline Usher and that she has inherited the crumbling mansion in a remote part of Georgia. Moreover, she discovers that she has a twin brother, the quick-witted and devil-may-care Roderick Usher. At first, things seem excellent-Mads meets a beautiful guy, Liam Delaney, who operates his father's farm down the road, she has inherited the remainder of the Usher fortune, and she now has a sprawling home, a place of her own.

However, Mads finds out that she's a pawn in a deadly game-her narcissistic brother is jealous of her romantic relationship with Liam, so he gaslights and imprisons his newfound sister within the haunted confines of the manor. Mads must battle against the inherited insanity that every Usher family member has succumbed to and embrace her hidden strengths that she didn't know she had to survive the madness of Usher House.

It appeals to gothic romance and horror fans-Twilight, Crimson Peak, and Dark Shadows.
