Orthogonal - The Clockwork Rocket, tome 1

Résumé : In Yalda's universe, light has no universal speed and its creation generates energy. On Yalda's world, plants make food by emitting their own light into the dark night sky. As a child Yalda witnesses one of a series of strange meteors, the Hurtlers, that is entering the planetary system at an immense, unprecedented speed. It becomes apparent that her world is in imminent danger—and that the task of dealing with the Hurtlers will require knowledge and technology far beyond anything her civilization has yet achieved.
