Someone borrowed, someone new…? In this Blame It on the Mistletoe story, conveniently marrying her best friend will give florist Millie the child she craves. Yet when her husband-to-be is called away on business, best man Giles comes to the rescue. Giles doesn’t believe in marriage. He’s learned the hard way that women only want his wealth. But this pre-Christmas rehearsal isn’t real, so he’ll happily step in for practice 'I do's. Trouble is, there’s nothing fake about the connection between this bride and her stand-in groom… With the big day looming, dare they speak now and find for ever—together?
