The front covers are really startling in their boldness. No title. No author name. No publisher's logo. Just fantastically striking and truly graphic images, combined with a great use of material and print process.
Of the three above, from left to right, Fairyland by Paul J McAuley uses a holographic foil and irridescent cover stock; The Separation by Christopher Priest uses an uncoated stock and a deboss; and Hyperion by Dan Simmons uses a spot varnish over black.
The spines and back covers have been given a series style with what looks like American Typewriter as the series typeface.
When you see what the previous cover was for Fairyland (below), you can see how radical a shift they've made. From a quick browse of a few online sci-fi forums it looks like existing readers aren't overjoyed at the new look, but that's really not the point - these covers are designed to reach out to a new audience who wouldn't dream of picking up the standard sci-fi book.
There are eight in the series, produced in-house by Emma Wallace, with a brief that was simply 'do what you want, but bring them to a new audience'. She's done that in spades.
