Twins, Jacob and Aron, can turn into a dolphin and an owl. They live in C’Wall, the closest point to the Wall, a thousand foot high upside down waterfall out at sea. They sit the exam for a competitive place at University for the Intentioned, both fretting that their powers are useless in real life. When only Aron gets in, Jacob makes a snap decision to switch their names and steal his brother's place.
The swap forces them to experience life from opposite sides of the class divide. Aron heads to a educational commune in Brixton, but does it have a darker purpose? Should Aron bring down the Wall, or does that make him a terrorist? And how far will Jacob go to stop him?
