Seeing as I have just read this and it is Reckless Day, I thought I'd compare covers.
I'm not sure with these two, as they are both amazing covers. The UK Portrays the golden goyle eye better, but the US portrays the jade skin better. For me this is a toughie so it all comes down to the fonts. The UK title font wins me over straight away, including the fact that it is foil. But then I love the frame around the US. For mr it's a draw but if I had to pick I would pick the UK. When I met cornelia she said to her they draw but is she had to pick she would pick US.
