Beneath Sequoia National Park’s towering giants, a secret world stirs—and it’s watching. Syrah Carthan, haunted by the wildfire that killed her parents and took her brother, accepts a historic role as the park’s first female fire chief. But a disastrous prescribed burn forces her to resign in shame.
When a new blaze threatens the forest, Syrah is drawn back and discovers a hidden society entwined with the forest’s ancient roots. Two factions vie for power: the Keeper, guardian of the sequoias, and the Undoer, a force bent on humanity’s destruction.
Caught between human loyalty and nature’s wrath, Syrah faces an impossible choice: save humanity or side with the earth’s vengeance—knowing either decision could alter the fate of the world forever.
