US // UK
I think I should apologise to Simon & Schuster UK because, this week, my vote is going to the US cover. I absolutely LOVE it. For me, it really captures the magic of Michelle's story, and I think the swirly font, unusual artwork and array of bright colours is responsible for that.
I do like the UK cover, mostly because the bracelet shown is a huge part of the story. The red makes it stand out, and always makes me think of the character Red, who is an important part of the series. I have to have the upcoming US cover, so I've pre-ordered a copy. I think it's going to look great on my bookshelf!
