I question how much of 'city' or 'urban' come into play with this. As is often the case, you get some works in these collections some are good, some bad, some simply resonate, and other's fall flat. So, as per the collection, it's gets a solid mediocrity at 3 stars.
Favorite story was "Ghost Market". Greg van Eekhout writes a very short, perfect, story - with an economy of words and expressions that emulate poetry in what he says.
The other's I thought were good and worthwhile were, "Sammarynda Deep" by Cat Sparks, which looking up I see has won a number of awards and I can see why, again, in this story the Author writes in a novel sized fantasy world into just a few pages.
The two of these I want novels on!
"Tearjerker" (Berman) and "The Age of Fish, Post-Flowers" (Tambour) where very good, but in their attempts at brevity and the creation of these whole worlds they get blurry, they lose their place, and the story elements become abstract.
"Courting the Lady Scythe" (Parks) was very good, well written, clear, but also completely obvious. By the third paragraph or so you know this story is only going to end one way.
Finally, "The Title of This Story", had me, it did, I was invested in the griminess of this city, in it's literate-ness, a story about stories, semi magical, and amazing. It ultimately doesn't go anywhere, however, it has almost no plot, no story. It's a nice city 'sketch' however, but poor story telling.
Honorable mentions in order of enjoyment are, "The Funeral, Ruined", "The Last Escape", "Painting Haiti", and "Godivy" just because the many moments of 'wtf... WTF... am I reading" make it memorable. Now I can't help but blush when see the copy machine....
