Having grown up in a household of elite, overprotective male Marines, Charlie Colebrook is savoring her hard won independence and avoiding a serious relationship that could tie her down. As a computer forensics expert for the DEA she might be a civilian rather than an agent, but she's far from helpless, and she's hungry to prove herself. So when her boss asks her to take on a dangerous undercover assignment that could expose the key money launderer for the biggest, and most lethal drug cartel in the Western hemisphere, Charlie seizes her chance. There's just one catch: the man assigned as her partner is the only man she wants...and he won't settle for less than everything she has to give.

Now he's the only one who stands between her and a ruthless cartel.

DEA Special Agent Jamie Rodriguez has tried like hell to ignore the explosive chemistry he has with Charlie. Not simply because she's his best friend's sister-but because with her, he wants all or nothing. As a member of the agency's elite FAST Bravo unit, he's got the skill and experience to keep her safe. Now that he's assigned to protect her on this op, he'll do it at all costs, even if she tempts him as no other woman ever has. But the final op tests them both to the breaking point, and when things go to hell, it will take everything they've got to survive the deadly trap set for them.
