I do! I both read and watch it, and love it!
.. The genre is: Adventure, Fantasy, Shounen, Supernatural (according to myanimelist xD)
taken from the wikipedia page: "Oz Vessalius, heir to one of the duke houses, has just turned fifteen. His life is rich and carefree, darkened only by the constant absence of his father. At his coming-of-age ceremony, however, everything changes. For no reason that he can discern, he is cast into the prison known as the "Abyss", only to be saved by a "chain" known as Alice, the bloodstained black rabbit. The mystery there begins as Oz unravels the mystery behind Alice, the Abyss and the strange organization known as Pandora. The series features heavy references to Lewis Carroll's Alice's Adventures in Wonderland and Through the Looking-Glass and can be considered both fantasy and mystery."
Maybe someone else can better explain what it's about though. I'm terrible at trying to describe/explain things, which is why i posted the plot posted on wikipedia. xD;
