The first translation of the book was published in Spanish by SM and went on sale in Mexico. I love the illustrations they've added throughout the book and the new title, 'The Biggest Secret of the Century'. 
The Polish translation has such at atmospheric cover. It perfectly represents the drama I was trying to convey at that moment of the story.
There also an audiobook version I'm pleased to say...
