Coveresque feat. Mercy by Rebecca Lim (AUS vs. UK vs. German)

I haven't read MERCY yet. I like the AUS and German covers, but the UK would be my favourite. I  heard MERCY is about angels so I'd say the UK cover is the most fitting and beautiful. It looks like the girl is wearing a skirt made of feathers and the white and blue harmonise perfectly. Have you read MERCY. Which cover fits the story best?
