She's soaked, her hair is matted, her skin is red, her eyes are closed and her arms are by her side. From her bare feet small roots have formed and reach into the ground, anchoring her. If we tried to pick her up now, we'd need a saw. It would hurt. It might kill her.

Bren works for an obscure company with colleagues he's never met, and who might not be real. His partner, Caelyn, is looking for something more but isn't sure what. The only thing she knows for certain is that humans are breaking the world and she's powerless to do anything about it.

One day Caelyn finds a group in a forest who believe that if they stand still for long enough they will become trees. And then she discovers another . . . The idea is spreading. Soon, people go missing and trees appear in unlikely places. Is it really possible?

As cities decay and the world becomes greener, Caelyn sees nothing to fear. Bren is not so sure. Finally, they must ask themselves what they're prepared to give up - and if they are ready to stand still.
