Recently divorced Gabby Greene spends most of her days listening to self-help books while wrangling her loving yet erratic kids. During a decade of marriage, Gabby shoved aside her own career and ambitions to make room for mountains of laundry, running errands, and investigating the case of the missing socks. Her number one suspect: their Bichon Frise, Mr. Bubbles.

All that changes when a secret government agency comes knocking on Gabby's door, asking her to go undercover. At first, she thinks some reality show is pranking her, but apparently, she bears a striking resemblance to an agent recently murdered, and... well, desperate missions call for desperate measures. Soon Gabby is juggling motherhood and a crash course in Spying 101, led by a handsome James Bond-type who has secrets of his own.

As Gabby embarks on a dangerous mission involving money laundering, a Russian oligarch, and an unfortunate incident with a prosthetic nose, she begins to realize that she is far from the invisible housewife she once believed herself to be, and that maybe, just maybe, she might be capable of saving the day.
