"The Drowning City," a model inspired from Book 4 of The Sea and The Wasteland, The Edge of All Worlds. There's an excerpt below from the chapter "Going Under," and additional images posted on the Art & Models page reflecting other areas within the novel.
On the underside of a narrow balcony, Rain and Alan came upon a small café table, wrought-iron chairs sitting in three inches of water beneath a green and white umbrella, abandoned.
Under the unchanging sky and the unending rain, time became an impossibility. Walled waterways led one into the next, a stitch-work of narrow paths and wobbling boards joined buildings across the current, the city really no different from the fens. In the bog, at least, he could see the way forward, even if it was only an impassable stone wall. The sinking city was a reckless, unending labyrinth, the dark water hiding an insidious undertow, a monster current eager to catch you, carry you down, drag you away like a freight train, lost forever in the cold and the darkness.
Or maybe the canals were simply an extension of the fens with savage, cadaverous beings lurking at the bottom, rotting and tormented and lying in wait.
