The photojournalist Thomas Volner is sent to Andalusia, to the heart of Europe's garden, a sea of plastic in the middle of the desert. Environmental devastation, slave workers: all of the ingredients for a scandalous story. But his investigation is disrupted by another case: after being kidnapped on their way to school, children reappear days later, hanging from the branch of a tree. A roman noir that is simultaneously historical, political, social, ecological, realistic, and humanitarian, Gilles Vincent masterfully plunges readers into a kaleidoscopic detective story.
