By a freak incident, plants on Earth have gained sentience and evolved into lethal organisms that can kill a human on touch.
Society has collapsed inward; humans live within the compact safety of The Fortress, a walled metropolis shielded from the horrors outside.

Phin, a mere Seed Appraiser, is thrust into the world of Botany, where he must rely on his encyclopedic plant knowledge to survive.
But when he unlocks a forbidden ability to harness the power of the brutal wilderness - the image that had for so long dominated his life begins to crumble.
