A medic who's used to treating bullet wounds discovers an undercover agent, or two, who want to heal her heart. As a medic for a team of do-gooder assassins, Kennedy usually patches up her partners after they've taken out some of humanity's trash. This assignment is totally different. She's required to risk both body and soul to seduce her ex, Knox, and convince him to double-cross the cartel he's worked for since he left her without a backward glance. Marcus has been addicted to Kennedy since they became partners at Shields. He can't turn away, even if it means watching her over their comms with the jerk who broke her heart and made her swear off relationships, including one with him. When Marcus and Knox form an unlikely alliance, to keep a new superdrug from ruining more lives-like they destroyed Knox's-Kennedy is forced to make a decision: continue to resist the potent chemistry they have together to protect herself or be brave enough to make up for the time all three of them have lost.
