Second Chances (Intrepid Heroines) by Andrea Pickens

For Allegra Proctor, tutoring the Earl of Wrexham's son has its disadvantages-namely the widowed earl himself. Arrogant, cold, and moody, Wrexham is also distractingly dashing. But Allegra only needs to to keep secret her real reason for taking a job in the wilds of Yorkshire long enough to right the wrong against her father, committed by the earl's dastardly neighbor. All is going according to plan-until the earl's son discovers her quest for justice and demands to help. But when their first foray runs into trouble, Wrexham is quickly entangled in the scheming. Having his quiet existence suddenly turned on its ear has Wrexham fuming, but he has never turned his back on a lady in distress. Together, he and Allegra draw up a scheme to ensure the villain is punished for his crimes...which awakens a second chance at passion that neither dreamed possible.
