A vibrant and emotional science fantasy about cousins trapped in mirrored worlds - the resplendent and verdant summer city and the ice-carved wastes of the winter city. For fans of Every Heart a Doorway and This is How You Lose the Time War.

Welcome to Jamie Pike' s Fairharbour - a city stuck in perpetual winter, its windows and doorways bricked shut to keep out the freezing cold, its residents striving to survive in the arctic conditions. Welcome to Esther Pike' s Fairharbour - a city stuck in constant summer, its walls crumbling in the heat, its oppressive sunlight a relentless presence. Winter and Summer alike, have both fallen under the yoke of oppressive powers, that have taken control after the cataclysm. But both Fairharbours were once a single, united city. And in certain places, at certain times, one side can catch a glimpse of the other. As Jamie and Esther find a way to communicate across the divide, they set out to solve the mystery of what split their city in two, and what, if anything, might repair their fractured worlds.
