Russian Prey (Assassin/Shifter #8)

Special Agent Keegan Ripley has watched, listened to and fantasized about the notorious Vicious Vince Markov for more than a decade. Now he has been assigned the task of going undercover in Rio to convince Markov to meet with FBI bosses about joining forces. After meeting Vince in a gay bar, Keegan finds that even his very close surveillance has left him completely unprepared for the man’s overwhelming sex appeal. Besides fighting his traitorous body, Keegan also has to deal with the fact that his crush is a complete and total ass.

Sexy, cold and unfeeling assassin Vince Markov is on a mission. He has been sent to Rio to kill Dario Nardozzi, a child killer whose number is up. He makes sure the psychopath knows he's in Rio, but it turns out that the biggest threat to Vince's well-being isn't Nardozzi - it's one Keegan Ripley. When he catches Vince's eye in a very big way, Vince is intrigued. But the beautiful Mr. Ripley isn’t interested and, thrown off his game, Vince has another mission: find out why in hell not!

Forced to work together, the mission becomes dangerous for both men. As they battle a madman and their own feelings, secrets are revealed, trusts are betrayed and lives are at stake. Vince's cold heart is in danger of melting and Keegan's resolve to resist Vince is buckling. Can a notoriously vicious killer and an FBI agent actually fall in love?
