The second season will not continue the story of Season one. This will tell a whole new story with different characters and it’s based on the 1898 novel by Henry James, The Turn of the Screw. The book tells the story of a governess, who will be played by Pedretti, “hired to look after a pair of siblings. However, several ghosts around their manor house exhibit a supernatural hold over the children.”
Here’s a description of the The Turn of the Screw novel:
A very young woman's first job: governess for two weirdly beautiful, strangely distant, oddly silent children, Miles and Flora, at a forlorn estate.
