Let's start with Unearthly by Cynthia Hand
(US, UK, Australia)
I think Cynthia Hand really won the cover lottery. All the covers are beautiful. But I think my favorite is the UK version. I find it interesting that the Croatian publisher added wings to the US version. Maybe they wanted to show the reader what the book's about?
Next: Sisters Red by Jackson Pearce
Both publishers us the red/black color scheme. What I really love about the German version is how creepy it is!
Most foreign publishers used some variation of the US cover, sometimes using different colors, sometimes different fonts. I like the black of the French version better than the light blue of the US version. It's more eyecatching. I'm not so cure about the "face-covers", especially the UK girl looks very young.
What are your favorites?
