The Lady in White by Chasity Bowlin

In the bucolic English countryside, Miss Louisa Jones finds herself thrust into a world of mystery and intrigue at Rosehaven Manor.

What begins as an interview for a companion position to an elderly woman takes a startling turn when Louisa discovers she’s been brought there as a potential bride for the enigmatic Mr. Douglas Blackwell.
As Louisa navigates the intricacies of her newly elevated station, she soon realizes that Rosehaven Manor holds secrets far darker than she could have imagined. Mysterious cold spots and chilling drafts haunt the corridors, while wraithlike apparitions appear before her very eyes. But it soon becomes clear that the true danger lies not in the ghostly whispers of the past, but in the present machinations of those around her. When Douglas’ cousin arrives, Louisa finds herself embroiled in a web of deception and betrayal that threatens to consume them all.
