Goliath and You're All Just Jealous of My Backpack also reflect his great craftsmenship, and I highly recommend you check them out.
Mooncop is a dark comedy/slice of life tale set on a lunar colony in some (not-so-distant?) future. It is the kind of comic Stanley Kubrick might have made, only by which I mean it shares a similar matter-of-fact sensibility about science fiction as well as an overall devotion to impeccable detail, craft, and style. The goings-on revolve around our titular police officer, whose job is not so fantastic or demanding as it might seem. There is surprisingly little happening on the moon, and the people who are there are law-abiding, so mostly we just see his daily routine.
2001 meets American Splendor, and that is actually quite a wonderful combination. The humanity and emotional life of the cop shine through all of the sci-fi trappings.
All of the reviews I have read of this book have sung its praises. Michell Buchman called it "a fun, clever meditation on what it means to be human." Greg Hunter wrote that it "may be best appreciated as a retro sci-fi tone poem, big on feel in its
depictions of loneliness and depression but short on insight." Oliver Sava remarked, "Gauld is known for his minimalist aesthetic and deadpan sense of humor,
and these two elements work wonderfully together to bring levity to the
emotional crisis in these pages."
Mooncop was published by Drawn & Quarterly, and they have a preview and more information available here.
