A detective and a lawyer are falling in love - and making a federal case out of it. When FBI agent Grayson Kincaid first encounters Olivia MacKenzie, she makes quite an impression. The beautiful, tough young attorney has stumbled into the middle of an FBI sting operation and reduced it to chaos. Kincaid's partner is furious and lets Olivia know that she's ticked off the wrong guy. After all, he's FBI. But Olivia isn't intimidated by his partner's bullying because she's something even scarier - she's IRS. And working for the IRS is no picnic. She's on the trail of an elaborate Ponzi scheme, one she has personal reasons to be angry about. But after she asks the wrong people questions, her life is suddenly endangered. She's accustomed to looking out for others who are weak, but being vulnerable herself makes her realise she needs help. In desperation, she calls Grayson Kincaid. They join forces to fight corruption, but Olivia is also fighting the immediate and intense attraction she feels for Agent Kincaid, and that may be a battle she is bound to lose.
