This third book of the collected edition contains volumes 6 to 8:
Ambassador of the Shadows - the story that directly inspired Luc
Besson's film - On the False Earths and Heroes of the Equinox. Over the
course of these titles, among the finest in the series, Laureline takes
her rightful place as the brains of the outfit, while Valerian fully
embraces his role as anti-hero: always brave, but often a bit out of his
depth. You will also find the end of the interview with Luc Besson and
the authors, and an in-depth portrait of Jean-Claude Mézières, the
artist.
