In this story, Jessica Hart employs one of her favorite plot twists; the hero and heroine who have to play at being engaged to each other for (basically silly) reason(s). The hero & heroine don't admit to each other that they are in love with each other, for (basically silly) reason(s).
Still, there is something realistic about these characters - they are likeable, ordinary people who hold down jobs, for instance - and the story has a sweetness to it (with appropriately witchy female sub-characters to give you someone to dislike), so that the book ends up being an OK read, if not as good as the author's "Blind Date Proposal". BLIND DATE PROPOSAL had a similar plot twist and similar warm & charming heroine paired with a cooler, somewhat uptight hero, but is a superior book to CHRISTMAS EVE MARRIAGE. I only just liked Christmas Eve Marriage and would recommend Blind Date Proposal over it.
