Le Dernier Éclat du Noyau

In 2041, the Earth is nothing but a vast open-air wasteland. Rivers are dead. Cities go dark one by one. Humanity kills itself over a jerrycan of water or a can of food. Money no longer exists - only calories have value. Elias is a technician. Every Tuesday, he makes the water run in the ruins of Lyon. That's all that's left of a routine, a life, a world that stopped working long before he did. Then he looks up at the sun.
And he sees the impossible. The magnetic pole reversal has just begun. Earth's shield collapses. Circuits burn out across the planet. Oceans turn against themselves. The sun, instead of setting in the West, climbs back into the sky - rising from the wrong side of the horizon. Somewhere in the Pyrenees, Dr. Aris Thorne may have the solution. A machine buried deep inside the Pic du Midi mountain, capable of restarting Earth's core.
If it works, the sun returns to the East. If it fails, the Pyrenees disappear in seconds. And someone must descend alone into the shaft, three kilometers underground, to pull the lever manually. That someone is Elias. A novel that begins in the ruined streets of Lyon and ends four billion years later in the silence of dead stars. A human and geological odyssey carried by unforgettable characters - a technician with no apparent heroism, a scientist who calculates until her last breath, a warlord who has lost his reasons to fight, and a prophet who worships the Western sun as a god.
A story about what we are willing to sacrifice to fix what we have broken. And about the question nobody asks soon enough - what if saving the world and destroying it were exactly the same thing?The second novel by Anass Sahli, after Le Dernier Adam. 25 chapters. A cosmic epilogue. An ending you won't forget.
