This week's competing covers are:
The US Cover The UK Cover
To be 100% honest, I don't like either of these covers. Yes, the bursting stars are pretty, but I think the almost-kissing couple doesn't portray the book very well, because romance was not the main element of the story. I really dislike the big white space on the UK cover, so out of these two I pick the US.
But the cover for the US paperback is my favorite. It's way more science fiction-y, and it depicts what the book is actually about better than the other covers.
