One rule oversees the post-apocalypse: never refuse a Harmonizer.
Storytellers claim there are two original stories. When a stranger named Eduardo, a Harmonizer with extraordinary powers, arrives with a warning, Rowan senses life is about to change. Eduardo warns that Haven City is growing and all those living in the expansion zone are in danger.
As the living world recovers from ecocide, the Harmonizers control cities to keep the human population in balance. But while the Harmonizers claim their actions are peaceful, Eduardo says they're taking too much and returning to the patterns that caused the world to warm.
Rowan decides to head out with Eduardo on a quest to warn others living in solarpunk communities that have fallen within the newly expanded city limits. Along the way, Rowan collects stories of survival and realizes fleeing the city will only encourage its expansion. Rowan and Eduardo must face the harm buried deep in their pasts if they're to have any hope of bringing the city to a halt.
