I have to say I really enjoyed the original hardcover but I much prefer the paperback. The only thing I dislike is when book covers change halfway through the series and then your books don't match. :/ That's kind of crummy. But I do think that the new cover design is quite nice and it goes perfectly with the cover for The Haunted ( August 31st, 2010)
Seems as though the new paperback version was possibly inspired by the UK cover.
