If only she wasn't his best friend and colleague's sister. That's about the only thing that gave him the strength to back away from the steamy encounter they shared. But now take-no-prisoners Maddie wants his professional help. And with her life on the line, all bets are off . . . Maddie's overprotective brother may have had her blackballed from getting into the FBI, but he can't stop her from conducting her own undercover operation-whether it's between the sheets with unforgettable Nate and his abs of steel-or on the streets, trapping a notorious drug lord. And when she combines the two, the result is explosive for everyone involved . . .
