Generations after the domes open, the healing world enters an unstable season of explosive growth. A parasitic signal infects the fungal network, forcing forests, plants, and animals into feverish overproduction. The result is a catastrophic "death grip" in which life is driven to reproduce itself to exhaustion.**Nyla**, a descendant of Elara's line and an immune carrier of the L0 engine, can resist the parasite's commands.
With **Theo**, a descendant of Sera's family, she journeys into the boiling tunnels beneath the earth to find the legendary fossil aquifers. These ancient waters hold microbial memory from before the parasite's rise. Nyla must risk her own life to bring the aquifer's cooling organisms into the parasite's core. When the fever breaks, the world returns to balance, and the Mitochondrial Summer becomes a lesson in stewardship rather than conquest.
