Silent on the Moor by Deanna Raybourn

In Grimsgrave Hall, enigmatic Nicholas Brisbane has inherited a ruined estate, replete with uncanny tenants and one unwanted houseguest: Lady Julia Grey. Despite his admonitions to stay away, Lady Julia arrives in Yorkshire to find Brisbane as remote and maddeningly attractive as ever. Cloistered together, they share the moldering house with the proud but impoverished remnants of an ancient family: the sort that keeps their bloodline pure and their secrets close. Lady Allenby and her daughters, dependent upon Brisbane and devastated by their fall in society, seem adrift on the moor winds, powerless to change their fortunes. But poison does not discriminate between classes.... A mystery unfolds from the rotten heart of Grimsgrave, one Lady Julia may have to solve alone, as Brisbane appears inextricably tangled in its heinous twists and turns. But blood will out, and before spring touches the craggy northern landscape, Lady Julia will have uncovered a Gypsy witch, a dark rider, and a long-buried legacy of malevolence and evil. Deanna Raybourn spins a gripping tale of loyalty and lust, set against the wild beauty of the Yorkshire moors.
