These Fleeting Shadows by Kate Alice Marshall

The Haunting of Hill House meets Knives Out in a bid for an inheritance that will leave Helen Vaughan either rich…or dead.

Helen Vaughan doesn’t know why she and her mother left their ancestral home at Harrowstone Hall, called Harrow, or why they haven’t spoken to their extended family since. So when her grandfather dies, she’s shocked to learn that he has left everything—the house, the grounds, and the money—to her. The inheritance comes with one condition: she must stay on the grounds of Harrow for one full year, or she’ll be left with nothing.

There is more at stake than money. For as long as she can remember, Harrow has haunted Helen’s dreams—and now those dreams have become a waking nightmare. Helen knows that if she is going to survive the year, she needs to uncover the secrets of Harrow. Why is the house built like a labyrinth? What is digging the holes that appear in the woods each night?And why does the house itself seem to be making her sick?

With each twisted revelation, Helen questions what she knows about Harrow, her family, and even herself. She no longer wonders if she wants to leave…but if she can.
