The Billionaire's Nanny (Harlequin Special Edition Book 2352)

TEMPORARY ASSISTANT…FULL-TIME FIANCÉE 

Just when he thinks "problem solved," internet billionaire AJ Cole realizes he needs more than a temp. He needs a fiancée to show off when he returns home to Haley's Bay for the first time in ten years. His family has a habit of matchmaking, and AJ doesn't need the drama. But as soon as Emma Markwell agrees to his assignment, he learns that pretend love can feel oh-so real. 

Once a nanny, Emma's played many games of make-believe. This shouldn't be any different—until a few hot kisses meant for show blur the line between fantasy and reality! AJ doesn't do commitment, but Emma has always longed for true love and refuses to settle for less. AJ can't resist a challenge, and soon, he can't figure out if he's just trying to get into her bed…or keep her from getting into his heart.
