Courtesy of Jussi at the Westeros.org forum, here are the covers for Daniel Abraham's two 2011 releases.
First up in April is The Dragon's Path, the first volume of The Dagger and the Coin:
Not bad. Possibly a little generic. The UK fantasy market is oversaturated with various brown-shaded covers featuring swords. It's not bad, it just runs the risk of getting lost on the shelves.
Next up in June is Leviathan Wakes, the first volume of The Expanse. Daniel Abraham and Ty Franck are co-authoring this under the pen-name James S.A. Corey.
This cover is quite nice, and puts me in mind of those excellent 1970s and 1980s SF covers by the likes of Peter Elson. Sounds like it could be old-school space opera fun.
