There are a lot of lovely historical romance covers that make me swoon. The Sinning Hour, the upcoming book in Elise Rome's Victorian Unmasked series, is a perfect example.
The color, the font, the pose, the pearls, and the cascade of dark hair, all work together to create one swoon-worthy cover. It makes me want to read this book. And that, my friends, is exactly what a book cover should do.
