Once the World Tree gave life. Now it hunts it. Cast from the heavens, Jonathan Roe awakens in a world unlike anything he's ever known-a living jungle that stretches for miles, woven through the colossal limbs of the World Tree. Separated from his friends and hunted by the savage Malrics who rule the deep wilds, Jonathan must survive in a land that is determined to tear him apart. But the World Tree-the heart of all life-has begun to rot from within. Once it sang with life; now it whispers with hunger. Its branches devour the civilizations that live upon them, its sap poisons the earth, and the creatures of its canopy have become monsters born of madness. At the center of the decay lies the Unmaking Tide and their Tiger King, whose plan is already in motion. If he succeeds, the World Tree will not simply die-it will awaken, reborn as a monster that devours the very life it once gave. To stop him, Jonathan must risk everything. Because if the Tree falls... all life will fall with it.
