I am SO not a comics reader (other than Asterix and TinTin, and a bit of Lucky Luke), but on the way to other things, I noticed that
Black Panther: The Man Without Fear (2010-2012) #516 by David Liss is free right now at Kindle, and possibly comiXology (???), as listed in the blurb. (David Liss also writes some pretty good mystery novels, including one Edgar winner, so I have him on my eReaderIQ watch list, but he seems to do a lot more comics...)
Anyway, I have no idea if this is of any interest to anyone, but since it's free, I figured I'd post it. If this isn't of interest in this thread, my apologies...
