“Hang on” are the words to describe their road trip, relationship, and love!

Healing from her injuries after helping to take down the Newburgh Slasher, FBI Agent Ashley "Mack" Mackenzie decides to vacation with her former partner and friend, Catlyn Lyte, before participating in her wedding. She needed to get her mind off her nightmares of the night her family was slain in a violent home invasion and the hot sexy dreams of her boss, Director Kyle Strong. Fun in the sun is just what the doctor ordered. That is until Kyle decides to accept Jack Gard's invitation to also vacation with them. How can she forget her inappropriate dreams about her sexy boss if he was underfoot? And she could do without his habitual reprimands while on vacation.

Kyle didn't understand his agent's constant failure to follow his orders or policies or her reckless acts to get the job done, catching killers, rapists, and the like. Nor did he understand his intense attraction and emotions regarding his agent. Almost losing Ashley to the Newburgh Slasher makes Kyle realize he wants a deeper relationship with her. Taking care of loose ends by breaking things off permanently with his on-again-off-again girlfriend, he joins Ashley on vacation to see if he can solve the mystery that she represented and to see where his attraction for her may lead. 

From minute one, their vacation is a high-action, thrilling, emotional ride with sexual chemistry off the charts.
