My Highland Lord — Tarah Scott

London Heiress kidnapped by the Marquess of Ashlund, read the headlines. Yet no one tried to save her. Phoebe Wallington was seven years old when a mass assassination attempt rocked Regency England. Her father was the only accused traitor to elude capture. Seventeen years later, the one man who could prove her father's innocence is dead. Now as a grown woman and a British spy, she's no closer to learning what really happened that day. Phoebe's quest for the truth takes a sudden turn when she's kidnapped by a suspected traitor. But Kiernan MacGregor, the Marquess of Ashlund, may not live long enough to stand trial. Someone wants him dead…and Phoebe stands in the killer's way. The only way to save her reputation and protect Kiernan is to marry him.
