Molly Harbison hates being asked "What do you do?" more than cleaning the ring around the bathtub or digging Cheerios and raisins out of the car's back seat. She's tried on every possibility from a flip Domestic Goddess to a simple declarative Mom. She jumps at the chance to make some extra money as a secret shopper. But when she's assigned to shop an online dating site...things get tricky. For one, she realizes her husband doesn't exactly meet her checklist of "must haves" for the perfect man, not at all like her dating site Mr. Perfect. For another, the FBI wants her to actually keep her date with Mr. Perfect, who just may be the perfect serial killer.
