Sunstone is a free graphic novel/comic book that debuted on Deviant Art and is getting a lot of attention. It was created by a husband and wife team (he's the artist, she's the writer) that goes by the name shiniez. They call it an "erotic romantic comedy" but it is considerably more than that and follows the BDSM exploits of two young women. Please be advised that the original material is sexually explicit and for that reason I'm not posting a direct link. Despite the subject matter, the artwork itself is high quality.
