Kate Emmanuel is terrified of getting hurt, so steers clear of emotional involvements: until she goes to stay in Liam Austin's house. Liam, an architect, designed and built the house that Kate falls in love with on first sight. She is also immediately drawn to the house’s owner. They appear to both have the same objections to marriage. 

The attraction between Kate and Liam reaches boiling point and, thinking there is no logical reason why two mature people can't enjoy a casual relationship, she agrees to an affair; with no emotional entanglements. But her attraction to Liam changes the course of her life, forcing her to toss away her convictions and follow the dictates of her heart.
