The Silent Curse of the Red Countess by Patricia Haverton

Winning what you want may cost you everything you love…

Persephone Sheridan guards precious cargo.
Her years as the caretaker of a comatose elderly noblewoman had always been uneventful. Until the day Lady Humbertson woke and bestowed upon her a mission that was never meant to be her own.
With a title that he never wanted for himself, Silas Galashields, Earl of Dornham, bears the guilt of his brother’s death. When a stormy night brigs a strange young woman right outside his door, he offers her shelter. Not realizing that he’s offering shelter to the darkness she carries with her.
Worlds apart and yet bound by the red thread of fate, they trudge the line between bliss and ruin.
When Persephone’s horse is found poisoned, the message is clear: the people she loves are next. Desperate to protect Silas from the shadow that follows her, she makes a grave decision: reveal the secret that Lady Humbertson entrusted to her. A bloody tale sealed in a scroll, older than the Crown itself…
