Earth is dying, and the most important academic year in Ellie’s life is about to begin. The divisive examination process of the ‘Level Twelves’ promises admission aboard the ‘flight-to-freedom’ programme, for those who pass. But what of those who fail?

When Ellie lip-reads two teachers discussing the possibility of the programme being abolished, she grows curious about the motives behind the faceless ‘Legion’. With mounting fears that Legion selection may come down to more stringent testing, and questions over the unexplained whereabouts of past students, Ellie starts to notice a worrying pattern.

Ellie’s distrust of everyone around her deepens when the dynamics of her friendship group are altered with a new arrival, but her fear for the future of mankind must take priority. With so much to lose, Ellie must find a way to save herself, as well as those closest to her to make sure she is not one of the very last generation.
