This week's competing covers are:
The US Cover The UK Cover
I certainly like the title font of the US cover better than the UK. Also, the book jacket is even prettier in real life than the picture online is, it's all shimmery and foil-y. What I don't like about either covers is that neither have strawberry blonde hair, which was Clara's natural hair color. Then again, the US cover model's hair is purple, so I guess it could be any color you want.
So, while the UK cover is very very pretty (love the foggy forest and light shining in), the US is the winner.
