Dangerous Promises by T.J. Kline
Just one more case... After her father's death, FBI Special Agent Toni Blades promised her fiancé she'd step down as an undercover agent. But that was before the biggest case of her career landed on her desk - a large scale, sex trafficking ring and she's tasked with finding its leader. It's only one last undercover job, what could go wrong? Las Vegas Detective Leo Castellano made the same promise to Toni and planned to keep his word, as soon as he closed his last missing persons case. But when his case overlaps with hers, it takes a turn neither was prepared for. The future Toni and Leo imagined is suddenly jeopardized and now, neither can walk away. Will they find the ringleader before it's too late, or will Toni's broken promise turn deadly?
