Wendy N. Wagner’s 2021 The Secret Skin is a stand-alone horror novella.
June Vogel of the Oregon Vogels escaped wealth (and exacting, impossible expectations) for the austere but rewarding life of a spinster artist. Escape proves temporary; her brother Frederick asks for her help. Having found a suitable replacement for his late wife Blanche, Frederick intends to enjoy a honeymoon with his new bride, Lillian.
That leaves the matter of Abigail. Who is to care for Frederick’s daughter while he is having fun? Not a nanny, for those tend to flee the family estate as soon as they can.
Duty overrides preference and prudence. June packs her things and journeys to the Vogel Estate, Storm Break.
