Okay, this one was on my kindle and I tried to read it because the premise hit my trope buttons. I made it about 68% in before quitting (and reading the last chapter for closure). Now, coming to the Goodreads page, I see it was a circa 90s Topaz novel, which TOTALLY MAKES SENSE. I might go back and give it another shot with that mind.
That said, despite the guilty pleasure catnip points (namely, childhood crush + mistaking-the-virgin-for-a-slut + hero-mortification-and-remorse-at-discovering-this-the-hard-way {huh huh I said "hard way"} STOP JUDGING ME THE FIRST ROMANCE I EVER STOLE FROM MY MOTHER'S NIGHTSTAND WAS A SILHOUETTE NOVEL WITH THAT PLOTLINE I AM A CHILD OF THE 70S OKAY), I couldn't completely work my way past the need for some heavy editing and the ridiculous mary-sue traits of an otherwise likable heroine. Sue me, I pretty much went into this book blind. But the whole King Henry's secret daughter, blessed by fairies thing was the last straw. And then, on top of everything that led up to 2/3rds of the book, the last chapter had battles at sea. CRAZYPANTS. Not necessarily in a bad way, I guess, but I'd have to be in the mood for it.
Good points: the author really loved her characters - you can tell. And the misunderstandings were short-lived enough to be tolerable.
