Sinfully Bound to the Enigmatic Viscount by Scarlett Osborne

Between lovers, betrayal is always the worst sin.

After her sister’s tragic memory loss, Lady Diana Dunkeld must endure the slew of suitors that her father pushes on her. But the youngest daughter of the Earl of Lutterhall rejects every single one of them.
With terrible rumors surrounding his family since his mother’s death, Elijah Saunders, the Viscount of Cambolton knows that finding a wife is going to be a hard task. Until the day he meets Lady Diana.
Social equals and yet worlds apart, they court their own ruin in each other. But they soon realize that their yearning for each other is not their only problem…
As new evidence of the death of Elijah’s parents comes to light, they find themselves in the middle of a conspiracy. When death knocks on their door, they can make only one wish…if only Diana’s sister could remember her accident.
