The Path of Thorns By A.G. Slatter

Alone in the world, Asher Todd travels to the remote estate of Morwood Grange to become governess to three small children. Her sole possessions comprise a sea chest and a large carpet bag she hangs onto for dear life. She finds a fine old home, its inhabitants proud of their lineage and impeccable reputation, and a small village nearby. It seems an untroubled existence, yet there are portraits missing from the walls, locked rooms, and names excised from the family tree inscribed in the bible. In short order, the children adore her, she becomes indispensible to their father Luther in his laboratory, and her potions are able to restore the sight of granddame Leonora. Soon Asher fits in as if she’s always been there, but there are creatures that stalk the woods at night, spectres haunt the halls, and Asher is not as much a stranger to the Morwoods as it might at first appear.
