The City Within is a dark contemporary slipstream novel written by Csilla Kleinheincz, a friend and an ex-colleague of mine.
This piece here is just an exercise in book cover design by yours truly: the book hasn’t yet been published in English (afaik), and the cover of the Hungarian edition is absolutely different. This cover in this specific form is, most probably, never going to get released, although the novel itself is rather likely to come out in English sooner or later. (Should you feel interested in it, click its title above to read an English excerpt.)
