The first light of dawn spilled like cheap wine across Kardashevia, greatest city in the Multiverse. It glinted through the crystal penthouses of the Helium Quarter, and painted with a warm orange glow the regimented hexagonal courtyards of the Hive districts, where the first yellow-furred gardeners were already hard at work, feeding the greatest city in the Multiverse. It heated the patchwork of tin roofs that covered Dagon Market, where human and kappa traders bustled about their business unaware of the pervasive reek of fish from everywhere in the Multiverse that surrounded them. The suburbs of Dronetown in the east, home to billions of stockbrokers and their slaves, already stood in full daylight even as the blood-drinkers of Spiketown, in the west, caroused under the setting moon. And there were places the sun did not reach. In the countless layers of the Undercity, a vast city in its own right, the sharp-toothed, crest-haired Mo'Locks were oblivious to the coming of day. The monolithic towers of the Shylords remained swaddled in their dusty cocoons of mammothspider silk. And then there was that /other/ city, that stood at right angles to Kardashevia - who knows what light shone down, or sideways, upon those appalling sentiences? Elephant-bird-drawn carriages rattled along the street in the shade of the nuclear monorail. Black smoke rose in a pall over the docks, where the Scrutineers were eliminating with extreme predjudice yet another outbreak of the Gnawing Plague. In the slums of Bogarttown, a shantytown the size of any normal city, mutated elvish children polished boots or begged for shells, huddling for warmth against the vast network of steam-pipes that linked all the reeking industries of the vastest city in the Multiverse to the vast, Hellbeast-fueled forge that lay beneath the vertiginous towers of The Spline.
That morning, in the most impossibly huge city any universe has ever known, Bobu Fokushein yawned and stretched as he peered out of the window.

R: The trend was cute to start with, but nowadays any time I see an SF/Fantasy book title with the word "City" in it, my eyes glaze over. Particularly if it's coupled with "greatest" in the blurb.]
