Copper Golems is the second volume of the sci-fi/fantasy series written by Matt Kindt and illustrated by David Rubin. I really think the main reason for the series is to give David Rubin the chance to create this bizarre, inventive world full of as many colors as possible, but Kind tries to match Rubin for sheer invention. The whole feels like a kind of wild adventure more than anything else.
Here, I found Rubin confirming my suspicion:
"Ether is a great excuse to draw all the stuff that I love like weird landscapes, monsters, creatures, and other bizarre things."
It's not about the story, so get over that worry; it's about fantastical creatures and color and adventure. The first volume focused on arrogant/logical adventure/scientist Boone Días in a kind of detective story, called to Ether to solve some mystery. Not much action, though.
The second volume poses another challenge/mystery to solve, but this one is more action-focused, as I said, an adventure, involving breaches/portals in the border between Earth and Ether. These are apparently not good, not sure why. Días doesn't believe in magic, there's a scientific explanation for everything, he gives up his family for this work, he's kind of a machine, though everything around him in Ether is magical and illogical and feelings. He's a kind of Sherlock Holmes type. But he seems to be kind of emotionally connected to Violet, who is gender unidentifiable and as crusty as he is. Interesting characters, with moral dilemmas. The emotional center of this volume is Días meeting his wife and daughter, who have aged on Earth as he has not in his time on Ether (he comes back to Earth periodically because he can't indefinitely survive on the food there, apparently).
Ether is a place of imagination and invention, where myths and magic come from, all anti-Holmes stuff. And weird ideas: Copper golems; a grumpy, spell-writing fairy; a lavender gorilla; a motorcycling spell-hacker. We're in one moment in a volcano, in the next in a desert full of living mummies and sphinxes, and then in a bizarre fairy forest. If this sounds like it might be fun to you to look at or read, if you have high tolerance for not knowing what the hell is going on, you are hereby invited to the madness. At its most basic it is about the struggle between myth/imagination and science as a basis for understanding the multiverse. Guess which side the storyteller and the artist come down on.
