The series is called A Dangerous Man, and the first book in the series is called Awakening.
Here's the description for Awakening.
Sophie Bennett has virtually no experience with men. Orphaned from birth, she's gone from living with her reclusive spinster Aunt to a sheltered education in a convent school. After her Aunt's sudden death, she is too busy trying to work out what to do with her life to even think of romance. Therefore nothing prepares her for David Preston, the intensely attractive business-man is entirely out of her league, but for some reason he seems to like her. Can she handle such a dangerous man, or is she in over her head.
