Book in French. Lift the veil on Mars' best-kept secret! As a scientist on a long-term mission to Mars, you've settled into your new life. You've even settled into a routine, much to your surprise. While you're out getting your mind off things, an old friend suddenly contacts you and sends you an old photo of yourself.

From contradiction to contradiction, from proof to proof, a terrible reality imposes itself on you: it seems that you are not alone on Mars...
