The City & the City, Miéville. Yes. This was my first ebook (from the library), which may have affected my experience somewhat, though not that I was able to detect. To get the editing complaints out of the way, there was a bad “whomever” that probably would have been on the first page of the paper volume. Later, there was a bad “whoever”, which doesn’t quite make up for it, and a “these kind”, which I believe I’ve never encountered before in an edited work. Finally, there were a number of places where hyphens were used where em dashes would have been appropriate, including at least one instance of an appositive set off by an em dash at the beginning and a hyphen at the end.
The story itself was adequately intriguing, with an unusual hook. Miéville drew out the explication of that hook just a little bit longer than was strictly called for, but it was not disqualifyingly long.
