DEEP COVER ASSIGNMENT After Holt McKnight's criminal informant disappears, the DEA agent must go undercover to get close to the missing man's sister, who may know more than she's letting on. But when Blair Sullivan's attacked, it's up to him to protect her—without blowing his cover. Blair isn't sure she can trust her new neighbor, Holt. After all, the last charming and handsome man she fell for was her late husband, and he turned out to be the brother of a ruthless drug lord. Yet when it's clear the target on her back is somehow linked to her past, she has no choice but to accept Holt's protection. Even if getting close is the last thing her scarred heart can handle.
