Would-be Christmas wedding

"Emmett Holt was laying everything on the line. The deputy director of Mission Recovery had gone way undercover to bring down a criminal mastermind. It had to appear, even to his own people, that he was involved in a plot to kidnap his boss's sister. But Cecelia Manning wasn't what he'd expected. Emotional entanglements made him vulnerable in his line of work. So Emmett made his heart as cold as a Christmas blizzard. But as Cecelia collaborated in his risky ploy, his admiration for her was surpassed only by his raging desire. He'd known from the start he could lose his career, but never imagined he could gain a wife."--Publisher.
