Book excerpt: Jonas Buchanan is a man renowned for being arrogant and seemingly emotionless, both inbusiness and in his private life. He never combines work and pleasure, and steers clear of any woman who doesn't play by his rules…. Rule 1: He doesn't bed virgins. Rule 2: He doesn't do Christmas. Mary "Mac" McGuire loves the festive season, and she's as pure as the snow falling outside Jonas's window. But by Christmas Day she might well have Jonas breaking every rule in his book!
