Valerian Graphic Novel Volume 23 Future Is Waiting

"Several new chapters of Valerian and Laureline's adventures - but are they flashbacks, or ? After the events of The Time Opener, Valerian and Laureline reverted to childhood, and are now living with Mr. Albert on 21st century Earth. But in a universe where time travel is a reality, words like 'after' or even 'now' can be somewhat hazy, and elsewhere, in other times, our young but nonetheless adult agents are still working tirelessly to maintain a galactic peace threatened as always by greed and the thirst for power."
