The Haunting of Ashburn House - Darcy Coates

There's something wrong with Ashburn House...
The ancient building has been the subject of rumours for close to a century. Its owner, Edith, refused to let guests inside and rarely visited the nearby town.
Following Edith's death, her sole surviving relative, Adrienne, inherits the property. Adrienne's only possessions are a suitcase of luggage, twenty dollars, and her pet cat. Ashburn House is a lifeline she can't afford to refuse.
Adrienne doesn't believe in ghosts, but it's hard to ignore the unease that grows as she explores her new home. Strange messages have been etched into the wallpaper, an old grave is hidden in the forest behind the house, and eerie portraits in the upstairs hall seem to watch her every movement.
As she uncovers more of the house's secrets, Adrienne begins to believe the whispered rumours about Ashburn may hold more truth than she ever suspected. The building has a bleak and grisly past, and as she chases the threads of a decades-old mystery, Adrienne realises she's become the prey to something deeply unnatural and intensely resentful.
Only one thing is certain: Ashburn's dead are not at rest.
