Life should be simple for Cassie.
For the small population of Earth survivors who live on the Space Station Hope everything they do is planned and scheduled, down to the cyclical food menus, their roles in the station, even how many children they have.
Despite rigid controls directing her life, Cassie feels more out of synch than ever and worries she won’t find a place for herself within the station community. Perhaps that’s because she’s hearing things inside her head that can’t possibly be real. Or maybe it’s the regular elopements of her peers, heading off to a romantic future in the Married Quarter of the space station, whilst she’s never even been attracted to a boy – no matter how hard her best friend Ami pushes them at her. Then there are the odd questions her work placement partner Balik keeps raising. His questions are just as troubling for her as his distracting smiles and eyes that seem to see inside her.
As Cassie draws closer to Balik she finds that everything else in her life begins to shift. He tells her things that call into question the system they live within. She can't believe he is right, but at the same time she finds it hard to deny the sincerity of his ideas. Could there be a connection between Cassie’s problems and Balik’s questions? The truth will drag them both to a terrifying and deadly conclusion beyond anything they could have imagined.
