Mitochondrial Spring. Mitochondrial series, #2

Forty-seven years after the freeze begins, **Elara** awakens from a fungal cocoon in a thawing city overtaken by fire weed, spores, and new life. As the first carrier of the L0 mitochondrial engine, she can communicate with the recovering mycelial network and survive the hostile outside air. She meets **Sera**, a descendant of Elias who has safeguarded the family's history beyond the Synthetic City.
Together, they discover that the dome-bound city has become a desperate relic of the old world, using cruel biological experiments and failing technology to resist change. Elara must decide whether her purpose is to destroy the city or help its people adapt. By exposing the city's Purge Protocol and opening the filtration domes in a controlled transition, she allows the spring to enter. The book ends with humanity's first painful steps into a new ecological age.
