Beyond the walls of the small village of Mythen Rood lies an unrecognizable world. A world where overgrown forests are filled with choker trees and deadly vines and seeds that will kill you where you stand. And if they don't get you, one of the dangerous shunned men will. Koli has lived in Mythen Rood his entire life. He knows the first rule of survival is that you don't venture beyond the walls. What he doesn't know is - what happens when you aren't given a choice?...

The journey through M. R. Carey's 'immersive, impeccably rendered world' (Kirkus) continues in The Trials of Koli - the second book of the Rampart trilogy. Koli has been cast from his village and into the strange and deadly forest beyond. But he heard a story, once. A story about lost London, and the mysterious tech of the old times that was there. And if Koli can find it, there may be a way for him to redeem himself - by saving what's left of humanity....
