Bliss House — Ann Jacobs

The derelict ante bellum house in the North Carolina mountains called out to Jill Carey, almost as if living beings compelled her to buy it and restore it to its former glory.
For good reason. It's inhabited by the ghosts of century-old illicit lovers, trapped in the place where they died until a descendant returns to Bliss House, finds a lasting love he is free to marry.
Kyle Randall, great great grandson of one of the ghosts, hates coming to the haunted house but agrees to restore the place for Jill, only to set in motion a dark, sometimes frightening tale of sexual obsession, ghostly intervention -- and the healing power of lasting love.
