The Wall by Gautam Bhatia

‘Imagine a horizon.”I can’t.’ 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.
