I just found this online, its the UK cover of the upcoming entry in the Shadow of the Apt series the Scarab Path, announced by Amazon.co.uk as being released in August 2010. The cover, illustrated by Jon Sullivan, is very appropriate to the the series. It seems to me that this cover resembles more what Sullivan has done for the US versions' covers for Pyr verses what he has previously done on books 2-4 for Tor UK. The Scarab Path cover has quite a bit more detail on the surrounding environment of the characters, something that has not really been present on Shadows of the Apt covers until now (though the Salute the Dark cover seems to be halfway between cover 5 and covers 2-3).

Check out an illustration only version over here, and you can check out other work by Jon Sullivan (including the other books' covers) over at his website.
