On Earth and in space, in the past and the future, greed and the thirst for power place Mankind in immediate danger. The two Galaxity agents’ investigation into the elemental forces appearing on Earth continues. While Laureline, dogged and efficient, follows a promising lead somewhere in outer space, Valerian is struggling to unravel the mysterious events plaguing our 20th century. Demonstrations of fantastic phenomena follow in quick succession, pushing poor Valerian to his limits. And matters will have to be settled simultaneously in New York and on an asteroid on the edge of the galaxy to save our world... Jean-Claude Mézières and Pierre Christin created "Valerian" in 1967 after working in the USA together, one as a cowboy, the other a teacher. While "Valerian" is Mézières’ only comic series, he has worked as an illustrator in many other areas, including designs and sets for "The Fifth Element," and he was awarded the Grand Prix du festival d’Angoulême in 1984. Christin also works in collaboration with other artists such as Tardi and Bilal and writes novels and film scripts.
