Mithila’s world is bound by a Wall enclosing the city of Sumer—nobody goes out, nothing comes in. The days pass as they have for two thousand years: just enough to eat for just enough people, living by the rules. Within the city, everyone knows their place. But when Mithila tries to cross the Wall, every power in Sumer comes together to stop her. To break the rules is to risk all of civilization collapsing. But to follow them is to never know: who built the Wall? Why? And what would the world look like if it didn’t exist? As Mithila and her friends search for the truth, they must risk losing their families, the ones they love, and even their lives. Is a world they can’t imagine worth the only world they have? For fans of Isaac Asimov’s Nightfall and Ursula Le Guin’s The Dispossessed comes an astonishingly powerful voice in speculative fiction that explores what it means to truly be free.

‘Did we not once promise that we would always be honest with each other?’ ‘I no longer ask for honesty. Just tell me a lie that I can forgive.’ After 2000 years, the Wall has been breached. As Mithila steps into a world unknown, her sister Minakshi tightens her grasp on a city bracing for chaos and violence under a red sky. The ghost of an old Revolution stalks the streets, while the shadow of a new one threatens to tear Sumer apart. Spreading word about this historical transgression, Alvar and Mankala find themselves facing new perils in a City they can barely recognise-one torn between old fears and new desires, while caught in a deadly power struggle. But soon, they will know that the crossing of the Wall has consequences not just for the City, but for the world.
