Quoting the Wikipedia article:
Les Fourmis (English: The Ants) is a 1991 science fiction novel by French writer Bernard Werber. It was released in English as Empire of the Ants. The book sold more than two million copies and has been translated into more than 30 languages. It was also taken to video game format.
Given the relative success of this I wonder why haven't more of his books and in particular the rest of the trilogy ever been translated into English?
Are there any statements about this by the publisher or the author?
