I have recently started reading Grimm Fairy Tales online thanks to Comixology. If you've seen the covers, you'd probably think of it as just eye candy, but even with art like this:
Grimm Fairy Tales is not risque re-imagings of old fairy tales. Yes, Red Riding Hood looks sexy, but the actual stories are darker and closer to the original versions than any bedtime story or Disney movie. Each issue features a frame story and the grim fairy tale depicted on the cover. The frame story shows the setup in the modern world and focuses on Sela Mathers, a woman who tries to help people by telling them the stories and purveying a message within that is meant to help change their lives for the better.
