In the quiet coastal town of Ashford, Oregon, Dr. Clara Whitaker returns home expecting to settle her grandmother’s estate, not uncover a scientific mystery beneath centuries old trees. When she discovers a patch of forest with rising underground temperatures, what begins as routine field research turns into a race to understand a hidden geothermal pulse warming the earth from below. As soil microbes surge and ancient roots respond, Clara must balance science, community fear, and her own unfinished past. When the Forest Warms is a powerful story of resilience, climate, and the fragile negotiation between nature and change.
