Book excerpt: The sole survivor of a climate apocalypse searches for his adoptive grandmother in the acclaimed French author’s “unforgettable epic” (Le Figaro). Winner of the 2020 Grand Prix RTL-Lire From earliest childhood, Corentin’s life is sad and solitary. Abandoned by his mother, he finally finds a home with Augustine, an old woman who lives deep in the Valley of the Forests. Years later, he moves to the city to pursue his studies—and discovers the dazzling pleasures and distractions of urban life. Around him, though, the world is on fire. Temperatures continue to rise, causing a permanent draught. The rivers of Corentin’s childhood have long dried up; the trees shed their leaves in June. A terrible catastrophe is brewing. The night when the worst happens, Corentin miraculously survives. When he reemerges from the city’s catacombs, he finds a devastated landscape, completely devoid of life. Human, tree, or beast: nothing is left. But Corentin doesn’t give up. Armed with nothing more than hope, he sets off on a journey to find old Augustine.
