In the New 52, Barbara Gordon can walk again and is no longer Oracle. This is not as bad as it sounds, according to the new 52 only 3 years has passed since she lost her ability to walk. I, personally, look at it as an alternative time line story to make sense of it all. Anyway, on to the review.
I think teenagers and above would like this, especially girls. It's great to have a strong female role model written by a woman, and that is rare in comics these days. A very good read, but warning, it does end on a cliffhanger.
