Christmas 1896 at the beautiful and secluded Longmoss House. Diana
Blount has lived here all her life - but since her father died, Longmoss
has lost its magic.
Now the money's running out, and Mother says
Diana must prepare to marry. This will be her last Christmas at
Longmoss, running wild with visiting cousin Charlotte and evading the
watchful eye of the one remaining servant, matriarchal housemaid Niamh.
Then
one day, in the shut-up East Wing, Charlotte and Diana's games and
ghost stories begin to get out of hand. The veil is thin at Longmoss,
and something is trying to get through - something with a Master to
serve.
