Richard Morgan's The Dark Defile cover art

Richard Morgan third novel in the A Land Fit for Heroes series, The Dark Defiles, may extend to four books instead of three and it will be released next year (August 2013).  For now, Morgan posted the cover art on his website:

The cover is interesting, although I'm surprised with the absence of blade. There is no synopsis available so far. Congrats to Adam at The Wertzone for being quoted on the cover!
