She runs on sarcasm and caffeine. He runs on silence and rage. Together, they're about to be someone's worst nightmare. Jade Warren is not military. Not law enforcement. Not impressed. As the only civilian at Under Lock and Key, a private security firm staffed by former Rangers, SEALs, and FBI agents, she has carved out her place behind a wall of screens, sharp wit, and a stubborn refusal to be underestimated. She does not do small talk, she does not do crowds, and she absolutely does not do brooding operatives with bad attitudes and falling wallets. Enter Logan Keyse. Fresh off a month-long undercover assignment and radiating hostility like a profession, Logan wants nothing to do with the civilian who calls him Fabio and hands him his ego on a plate before breakfast. But when a dangerous case collides with Jade's past, dragging a former high school love into the crosshairs of a deadly criminal operation, Jade and Logan are forced into a partnership neither of them wanted. The deeper they dig, the more personal the threat becomes, and the harder it gets to pretend that friction is all they feel. In a world of gray ops, buried secrets, and lethal stakes, Jade will have to prove she belongs on this team, not just behind a desk. Because the danger closing in does not care that she is a civilian. And neither does the man who is starting to realize she might be the most capable person in the room.
