I wake up, and for a few precious seconds I don't realise there's anything wrong.

The rumble of tyres on bitumen, and the hiss of air conditioning. The murmur of voices. The smell of air freshener. The cool vibration of glass against my forehead.

A girl wakes up on a self-driving bus. She has no memory of how she got there or who she is. Her nametag reads CECILY. The six other people on the bus are just like her: no memories, only nametags. There's a screen on each seatback that gives them instructions. A series of tests begin, with simulations projected onto the front window of the bus. The passengers must each choose an outcome; majority wins. But as the testing progresses, deadly secrets are revealed, and the stakes get higher and higher. Soon Cecily is no longer just fighting for her freedom - she's fighting for her life.
