Jack of Hearts — Sandra Owens

Alex Gentry doesn't scare easily. Working as an undercover FBI agent in the biker bar he and his brothers co-own, he hangs with deadly criminals in order to gather information. Danger is just part of the family business. But one thing has him terrified: his attraction to Madison Parker.

Madison is the cousin of Ramon Alonzo, son and second in command to a notorious drug lord Alex is trying to bust. Alex has befriended Ramon as part of his cover, and Madison has unknowingly become his informant. Falling for her could risk this case -- and both their lives.

All Madison wants is to get her new bookstore business off the ground, and for her creepy cousin Ramon -- to whom she's unfortunately indebted -- to leave her alone. If she could only stop fantasizing about his mysterious new friend, Alex…

As the Alonzo cartel investigation heats up, so does their relationship. But will the secrets they're keeping tear them apart -- or get them both killed?
