Thank you for the pointer! I picked up the TPB (well, it was actually a hardcover), and that's gorgeous work.
I'm pretty much an "instant buy" any time I see Mack or Keane as illustrator. I think the guy who's doing Queen of Angels is in a similar league... which is a whole lot less surprising, given that (s)he's apparently reasonably well-known. I love it when a big company gives someone with that kind of talent the freedom to do a whole book by themselves. Can you imagine what the negotiation with Marvel was like when Mack told them he wanted to do that book?
I'm glad you liked it.
