Ruthless Cross (Off The Grid: FBI #6)

Everyone has a secret. Some are worth killing for…some are worth dying for…

FBI agent Flynn MacKenzie is no stranger to deception, but when the brutal murder of a federal judge unravels an intricate and shocking web of lies, he finds himself tangled up in personal life-changing secrets and in the arms of a woman he isn't sure he can trust.

Callie Harper not only wants justice for her stepfather, she also wants to protect her family. Staying close to Flynn seems like the smart option, until she starts to fall for the man who could hurt everyone she loves. 

The lines between good and bad, guilty and innocent, are blurred. Callie and Flynn quickly realize their search for the truth could take them somewhere they don't want to go...if they can stay alive long enough to get there.
