The House of Dead Maids by Clare B. Dunkle

Young Tabby Aykroyd has been brought to the dusty mansion of Seldom House to be nursemaid to a foundling boy. He is a savage little creature, but the Yorkshire moors harbor far worse, as Tabby soon discovers. Why do scores of dead maids and masters haunt Seldom House with a jealous devotion that extends beyond the grave?

As Tabby struggles to escape the evil forces rising out of the land, she watches her young charge choose a different path. Long before he reaches the old farmhouse of Wuthering Heights, the boy who will become Heathcliff has doomed himself and any who try to befriend him.
