Kaleem Malkendy is different – and on Terrestra, different is no way to be. Everything about Kaleem marks him out form the rest: the blond hair and dark skin, the uncomfortable cave where he lives and the fact that he doesn’t know his father. He’s used to unwelcome attention, but even so he’d feel better if some strange old man didn’t keep following him around. That man introduces himself and begins to explain the Babel Prophecy – and everything in Kaleem’s life changes forever.
