Dark Knights of Steel, Vol. 1

I actually thought this was really good! I'm not the hugest DC fan outside of Batman, but I appreciated the different take on the Superman origin story where the Els have set up a whole kingdom, Bruce is a bastard son, and there's a rival kingdom wanting to bring the whole thing down. There's some really great art here as well, hats off to the artist.

I think my favorite part about this entire thing is Harley's role as an advisor of sorts to Bruce. She's still unmistakably Harley, but there's an undercurrent of actual wisdom and concern to her advice that I appreciated as being different and special.

Just a fun Elseworlds medieval tale, highly recommend.

Really interesting What-If kind of story.
Best read all at once so you don't lose track of the characters.
