I kissed a rogue

When the Duke of Lennox hires Sir Brook Derring, England's best investigator, to find his daughter, Brook intends only to rescue the lady and return to his solitary life. He deals with London's roughest criminals every day of the week; surely he should be able to endure seeing his first love again--the perfect girl who broke his heart. Lady Lillian-Anne Lennox has always done her best to live up to her father's standards of perfection--at the cost of following her heart. When she's kidnapped and her perfect life is shattered, Lila has another chance. Together, Lila and Brook navigate not only the dark and deadly side of London, but the chasm of pride and prejudice that divides them.
