Cave [EPUB ebook] 

Cipriano Algor, an ageing potter, lives with his daughter and her husband in the shadow of the Centre, a nebulous, constantly expanding conglomerate that provides his livelihood until it decrees that it is no longer interested in his humble wares. Together with his daughter, they craft a new line of small ceramic figurines and, to their bafflement, the Centre orders vast quantities. But once the figures are complete, the Centre recants: there is no market for them. Resigned to idleness Cipriano moves into the soulless megaplex, until late one night he comes across a horrifying secret in the bowels of the artificial city.
