Jacquie Morgan is an open book...
Married young and widowed soon after, Jacquie can't remember a time that she wasn't defending and protecting someone. When her baby goes to college and her nest is empty, she decides to indulge herself. Attending the F5F Valentine's Day "come disguised as your favorite superhero" party seems like the perfect solution—but the better one is taking "Superman" home for the night, knowing exactly who is behind the mask.

Pierce Aston has a hidden past...
Pierce is building himself a new life, with no commitments or responsibilities. Flatiron Five Fitness should be the perfect place to find his new balance, with the bonus opportunity to admire kickboxing queen and human resources manager, Jacquie, but he knows he needs more. Going to a party in disguise is right in his toolbox, as is a mission to provide her with a night of seduction—but being with Jacquie is far more addictive than Pierce expects. When she admits that she only wants a fling, how far will he go to convince her to try for forever—or will his past threaten their chance of a future?
