The Alien Outlaw by Magda Rhodes

It’s my first day on the job, and the FBI wants me to seduce a Vogdian.

Sasha: The FBI says the Vogdian carries a deadly virus. They recruited me to seduce him, tranquilize him, and turn him in. All of America is at risk. But the bond between human female and Vogdian male is an irresistible mix of love and lust. I must put aside my feelings and do my duty… unless the FBI is lying.
Kaz: My people are dying. A true Vogdian has not been born in 100 years. I suspect the councillors on my home world, Ellia, are behind it all. My rebellion will overthrow them, but first I must find a bride on Earth. Once we mate, she will not be able to resist. She will be mine.
