Westfield Comics' Josh Crawley takes a look at Previews #257:
Ron Marz brings the Necromancer into the fold this issue. Not sure who she is? Sounds like a great opportinuty to check out the Necromancer softcover, featuring some great Francis Manapul artwork! Not sure who Witchblade is? Why not check out Image Firsts: Witchblade #1!
Not sure who Magdalena is? Thanks to Marz, she’s had a resurgence in the Top Cow universe, and now she gets a new ongiong series! Sadly, I can’t find our listing for the Magdalena Volume 1 softcover, but Darkness Volume 3 and Magdalena Blood Divine contain her early major appearances. For a more recent appearance, check out the First Born softcover, or the Witchblade Volume 5 softcover!
