"Seventeen-year-old Denise Farber, her mom, and her stepfather are moving back to New Orleans, into the Argonne house, which is over 150 years old, and really showing its age, but which her mother plans to turn into a bed-and-breakfast--but old houses have histories, and sometimes ghosts, and a mysterious old comic book that Denise finds in the attic may hold the answer to a crime and the terrifying things that keep happening in what she thinks of...

The haunting starts even before Sophie arrives on the Isle of Skye to spend the summer with her cousins, but when she arrives she finds a house haunted by the ghost of a girl who attended school there a hundred years ago, as well as cousin Rebecca who died young and is never mentioned by her family--and she must somehow solve the mystery of the frozen Charlotte dolls before the whole family is destroyed.

Sixteen-year-old Cordelia and her family move into the house they just inherited in Pennsylvania, a former insane asylum the locals call Hysteria Hall--unfortunately the house does not want defiant girls like Delia, so it kills her, and as she wanders the house, meeting the other ghosts and learning the dark secrets of the Hall, she realizes that she has to find a way to save her sister, parents, and perhaps herself.
