Story was somewhat interesting but I didn't care for the art style. If you area Raven fan, you'll probably enjoy it as it establishes her in her new "life"
I didn't read it but from what I heard NO ONE liked the art (and some people stopped reading because of it) and for those who could deal with the art, the story was ok. Mainly because it was really really hard to get past the art.
If you are a really big fan (and again, most people who finished reading the mini thought it ended up being a good story) flip through it before you buy anything and determine for yourself if the art is too much of a turn off.
