When Emily gets chosen for a special undercover assignment, she has every right to worry. But when she finds out the assignment involves more than just crawling into bed with one of the Agency's most wanted, she doesn't know how to respond.

Because the assignment isn't about short skirts and a ditzy attitude. It's about dressing up like a little girl and regressing for Gregory Vilichenko, a dangerous Russian mob boss who loves Age Play. The mobster will treat her like a child, and punish her when she's bad. And if things go south, Emily knows that the mob boss likes to diaper up the naughty girls.

Now her only hope of getting through the mission is to get into character. And when Emily's boyfriend Daniel decides to regress her before her mission, the petite agent can't say no. She'll be Daniel's baby girl for the night. She'll wear diapers and suck on a pacifier. And by the end of it all, she might just have the skills to fool Vilichenko.

Emily can only hope she is ready for the mission. One that could make or break her career. But if she isn't the perfect little girl of the Russian gangster, she might never walk out of his house again!
