This is the Orbit (US) cover of the new Joe Abercrombie book, it's out in hardcover in November. I think the cover is OK, but the font is pretty big and obscures much of it. You can read more about this cover in a post by Lauren Panepinto here.
NOTE: The UK edition will be out from Gollancz towards the end of September.
This i an omnibus edition of Maurice Broaddus' trilogy, coming in September in the US and October in the rest of the world from Angry Robot Books. The cover is by Joey HiFi, and like the rest of the covers I have seen by him this is a really good one.
A new Culture novel by Ian M. Banks, coming in October from Orbit. I really like Banks' Culture novels, and am excited that there is a new one coming this year. With luck, and maybe a time-turner, I will be caught up with the series when this one comes out. The cover looks pretty good, suitably futuristic.
This cover by Ana Juan is for the second Fairyland novel by Catherynne M. Valente. It looks great, and will fit in perfectly with the cover for the first book on my shelf. The style of both these covers are really great, and as I have the first one I can attest that these look even better in real life than they do as a photo.
From Night Shade Books we have the cover for The Book of Cthulhu II, edited by Ross E. Lockhart. The Cthulhu silhouette in the background is just awesome. Really shows off the best side of Cthulhu, at least the one you can see without going crazy in the process.
