Synopsis: "A space opera of powerful originality that questions our hyper connectivity and our relationship to the environment. Thanks to the Phytoid De Katz, a prodigal and mysterious tree, humanity has conquered a good part of the galaxy. The Egregore, a sprawling communication network, synchronizes the time of men and vibrates their over-connected souls to the sound of the same tuning fork. Recluse in the artificial jungle of the Okodrée plateau, Thyra, a young ethnologist, studies a people returned to the primitive state following the shipwreck of their distant ancestors. At the antipodes of this small moon, in the suburbs of a mining city, Roonis tinkers and traffics in various "psyentific" gadgets. Life goes on peacefully, until the enigmatic Egregorian authorities demand the unthinkable: the murder of an old native. This crime, the young researcher can not solve it. Accompanied by Roonis, hunted by the Egregore, Thyra embarks on an incredible interstellar adventure." Amazon France April 10, 2022
