Being old and grumpy I don't have the resonance to Stephanie, though I mostly think she is an okay character. It seems like she could be a modern version/pseudo version of Bette, considering the blonde, but I don't care that much.
The cover is adorable, of course and to me, shows the Nightbird/Flamebird aspects; dark and light.
I guess this is reflected in Tim and Steph, now that I think about it. Maybe they should become NW and FB, lol
and Dick should be Robin something else, and Bette could be Mistress of the Bats, lol (hey, Halloween is coming1)
