The City of Shifting Waters: Valerian Vol. 1 - Pierre Christin To my great surprise this series is being re-released in English! Buying them and re-reading them as they are coming along. They are as awesome as ever! :-)

EDIT 29/07/2013:
Luc Besson is adapting this awesome series into a movie!! Is this cool or not?? I'm definitely looking forward to this release, whenever that may be!
