In the past 5 days I've received two books from France by Benoit Sokal: one is a hardback edition of his comic book series " L'Inspecteur Canardo, tome 5: Amerzone" and the other book is " Lost Paradise of Maurania." Of course, both books are in French, but it was the art I was after.
The Paradise book is especially nice - lots of pencil sketches, concept art, finished paintings, and screenshots from the game.
I consider both books excellent additions to my book collection.
I found both books, and many other Benoit Sokal books, at "www.abebooks.com". They're even selling his game "Sinking Island" and a book about Syberia. Some of the books look to be in German and some in Dutch.
