I think I've lost track of my reading.
I read China Miéville's The City and the City. Cool idea, but it ended up being a bit of an anticlimactic, nearly straight-genre mystery. I think the book's core was his story "Reports of Certain Events in London" stretched out to book length. "Reports" is a terrific short story about a Pickwickian society of people who study feral streets, i.e. streets that don't tamely remain in a particular place but wander around.
Of course, The City has a completely different premise and purpose, but has a similar feel or feel of intention: to mess with the structure of cities using a surprising novum. And to introduce a mystery that can only happen within that particular situation. And I think this ... idea? structure? purpose? ... was better served in the short story than in the novel.
But still a good read.
Also re-read Austin Grossman's Soon I Will Be Invincible and it really holds up. Well structured and thought out. Insightful. Fun to read. Some minor glitches with the representation of the female protag, but altogether a good job.
And I think I'm missing something. Arg.
