Well, that was preposterous and not in the fun way. First of all, it's riddled with errors. The aristocratic titles were all wrong, there were tons of typos and missing words. If this is a good example of a Signet Regency, I don't think I need to read any more.
Really though I was just bored. I have limited patience these days for ballrooms and bloodlines. I thought this was going to be a marriage of convenience story where they get married and learn to like each other. I love those. Instead we get an interminable engagement (probably to avoid any reference to even marital sex) and a series of silly escapades, primarily by the heroine, to attract her insta-beloved's attention.
Frankly, I didn't see what either of them saw in the other. The hero is high-handed, perfectly calculated to make the sassy, independent heroine crazy. And she's both naive and stubborn, never a good combination. Besides their physical attraction to each other, which was never consummated because it's a trad Regency romance, they never seemed to like each other much. Add in a totally contrived crisis ending and I can say I'm officially less than impressed.
At least the plot, such as it was, proceeded apace. And the hero and heroine's families were both lovely and engaging, which kept the book from being a total waste of time.
I have another of these, that one by Edith Layton. I'll read it eventually probably. But it's distinctly probable that these just aren't for me.
