Wow! Check out this line-up of seemingly Twilight-inspired covers on classics put out by HarperTeen. Pride and Prejudice by Jane Austen, Wuthering Heights by Emily Brontë, and Romeo and Juliet by William Shakespeare, quite a triptych, eh?
Here's the British edition of Wuthering Heights by the same publisher. It's billed as "Bella & Edward's Favourite Book."
And here's a cover for Charlotte Brontë's Jane Eyre by Amazon's publishing house, CreateSpace. Look familiar?
Okay, these last few aren't classics... but the cover of Kissed by Angel, by Elizabeth Chandler looked so Twilight inspired, I had to include it. The American edition is on the left, the UK edition is on the right. I don't think you can see in this picture, but the British edition also has the tagline, "True Love Lasts Forever" in tiny lettering at the bottom.
And here, the cover for Sleepless by Cyn Balog, also features a flower on a black background.
