The world of Lethra is growing cold. Flame, once drawn from living things, is now fading. Entire cities have gone dark. In a mountain village clinging to survival, a young girl named Sera is born with an impossible gift: she can start fires with a single breath.
Sought by kings, prophets, and heretics, Sera flees with a disgraced knight and a blind scholar across a world in collapse. But the more Sera uses her power, the more she realizes something inside her is waking up. And it may be the very force that doomed the world to begin with.
