What is the anime Black Butler about?

My friends have suggested I watch Black Butler, and I have seen some pictures of it while browsing online. Plus, it seems like everyone thinks it's good AND I want to have a new, fresh anime experience! So, can anyone summarize it for me? Is it like Higurashi, though? Because I found that disturbing and didn't like that anime. It... ahem, wasn't my taste. Ok, thanks!! (:
