I haven't read one of Christine Warren's books before. I picked it up on a whim and, based on the summary, the hope of a leprechaun subplot (alas, that is a lie).
If you like bitchy, unlikeable heroines who hate everyone and heroes with no personality beyond being creepy, possessive assholes, you will like this book. The heroine, Corinne, is supposed to be "smart" and "sassy," but she never shows it. She just shows that she is an idiot and a jerk. She's a jerk to people she has just met, she's a jerk to her boss, she's a jerk to her friends, she's a jerk to her lover... She's not what I would call a likeable lead.
Luc, the hero, is basically just a fairy beefcake who has no personality beyond Neanderthal-like desire to have lots of sex with Corinne and force her to be attached to his side forever.
I should mention, Warren skips the need to build attraction between her characters by telling you how much they lust after each other even though they don't seem to like each other at first. The whole novel only covers about a week or so, and that they would become so in love in that amount of time is bizarre. Warren found a great way to get out of all that romantic chemistry stuff by making it all about how Fate wants Corinne and Luc to be together. This means that neither of them has any choice in the matter. They have to be together for all of eternity. That's kind of creepy, and because of that none of the romance really feels like romance. It's just sex and the writer telling you they love each other so much because of this whole fate thing, but you never really feel it.
The two spend most of the novel unable to function as the plot requires because they can't control their lust for one another. This really gets old when the chemistry isn't strong, and after a certain point it just becomes absurd.
The plot is weak. I don't expect much from romance novels, but it was weak. It appeared and disappeared whenever it was convenient. Corinne's reporter job that was so important in the beginning also conveniently disappeared about halfway through. You never hear about it again.
The writing was rather poor. I have an immediate dislike for authors who overuse fragments to create tension or for emphasis. This is pretty much the only way Warren builds tension. Oddly, her style got smoother and less irritating in the sex scenes. Why she can't keep that up for the rest of the book is beyond me. The book also needed another go for editing. There were several typos, a lot of repeated phrases, and just a general lack of polish.
I did not like the male/female dynamics of the book. All the women were gossipy and useless, and really terrible friends to each other. The only thing they ever talked about with one another was men, which should be a red flag. Speaking of red flags, you could have stuck some all over the guys in this book. They were all controlling and possessive and were always humoring the silly antics of their women. Warren makes gestures toward the women not being OK with this, but any time they speak up, you get the whole strong-man-humoring-silly-woman thing. There's no way I would find any man with an attitude like that attractive, regardless of what he looks like (or what I'm told he looks like). Her men fall flat as romantic heroes, and her women are too weak and unlikeable to be good romantic heroines.
Not Your Ordinary Faerie Tale is readable, but it's not very enjoyable unless you love nonsensical/magically disappearing plots and reading what sounds like the start of an abusive relationship. I would not recommend it and I don't believe I would pick up any of the author's other books.
