I've mentioned a couple of times that Power Girl, costar of Worlds' Finest with Huntress, crossed over with Supergirl this week. I have not read the issue myself, but I did read the preview, and it was awesome. Here is a review I thought was well written of the actual comic. Maybe this might push some of you on the fence over into a purchase. If you scroll down, there is also a review of the latest Batgirl which is fairly good.
