I'm in the process of doing a cover update for the next printing of City of the Lords. The cover artist, Jeremy Gregory, originally gave me digital art which I used for the initial printing. Since then he has also given me a painting which better matches the style of the artwork for Lord of the City. I'm in the process of changing out the cover image; once I get the proof in the mail and approve it any future copies of City of the Lords will come with the new cover image.
Other than the cover image swap, there will be no differences in the printings.
