Fiction by Tatiana de Rosnay.
I disliked the main character of this book most of the time; however, that doesn't mean I didn't like the book. That's an interesting thing, because usually I wouldn't want to read about an unsympathetic character.
This was an unusual story, as it was basically about a guy with writer's block, but I enjoyed it.
I also read by this author: Sarah's Key, A Secret Kept, The House I Loved
