After a summer spent in a
haunted
castle—a summer in which
she traveled through time to solve a murder mystery—Kat is
looking forward to a totally normal senior year at
McTernan
Academy. Then the ghost of a little girl appears and begs
Kat for help, and more unquiet apparitions follow. All of
them are terrified by the Dark One, and it soon becomes
clear that that this evil force wants Kat
dead.
Searching for help, Kat leaves school for the
ancestral home
she’s only just discovered. Her friend Evan, whose family
is
joined to her own by an arcane history, accompanies her.
With the assistance of her eccentric great aunts and a
loyal
family ghost, Kat soon learns that she and Evan can only
fix
the present by traveling into the past.
As Kat and
Evan make their way through nineteenth-century
Vienna, the Dark One stalks them, and Kat must decide what
she’s willing to sacrifice to save a
ghost.
