US // UK
I'm not sure I have a favourite cover this week, I love each of them for different reasons. Both covers make the book look like a poignant read (which I believe it is, from reviews I've read), and I like both title fonts used.
The US one probably stands out slightly more due to the use of the red, though I really like the simple effect of the clouds on the UK one. I'd buy either... how about you?
