Her Rogue Russian by Leslie North

Former Russian mobster Maxim Karev is a man with something to prove. His father’s been murdered and even his own brother thinks he’s guilty. To clear his name, Maxim has to return to the organization he left behind. He likes to work alone, but this time an FBI agent leaves him little choice—either she goes in undercover with him, or Maxim can rot in jail. One thing’s for sure—he’s not going down for a crime he didn’t commit. If playing with the beautiful agent is what it takes to prove his innocence, Maxim is prepared to go the distance.

FBI agent Savannah Casillero never backs down. She already lost her partner on this case, and now she’s more determined than ever to find Sergey Karev’s killer. With the Mafia’s former head of security under her thumb, she finally has a way inside—as Maxim’s girlfriend. Controlling the lone wolf may be a bit of challenge, but Savannah’s confident she can handle it. The six-and-a-half-foot Mafia man is certainly not her type, but she’ll do more than play along to make it believable.

They’re willing to work together to track down a killer, but when the ruse becomes a little too real, will Maxim and Savannah give in to temptation or hold fast to their original obligations?
