...that Of the City of the Saved... is technically now in release, although as far as I'm aware there are no copies in the UK as yet.
Do buy it, someone's already described it as "absolutely brilliant". And that was on the Faction Paradox discussion boards, so he can hardly be biased or anything.
Anyway. There are some Extras pertaining to the novel, including Deleted Scenes and Commentary, up on my website. More Commentary will follow once I have a real copy to work from.
