Her Secret Lover by Sara Bennett

Desperate to save her reputation, the beautiful heiress Antoinette Dupre escapes to Wexmoor Manor, a country estate in Devon. But she gets more than she bargained for when she encounters a masked stranger who, with just one touch, awakens in her an irresistible desire.

Gabriel Langley is on a mission. Antoinette has a letter he needs to take back his family's ancestral home, and he is willing to go to any lengths to claim it—even seduce her. And though aware he is playing a dangerous game, he cannot resist returning to her bed in the shadow of darkness . . . to become her secret lover.

But when Gabriel's true identity is revealed, their passionate midnight interludes are threatened. And they must face a web of scandal and blackmail that could destroy their one chance for love . . .
