All pupils at Stoneyridge School have Review sessions. The students don't enjoy them, but understand they are used to improve their well-being and are simply a part of school life.
Zane Sampson is one of these students who has learnt to live with Reviews; however, after discovering that the school is secretly using these sessions to mark its students either as Eligible or Ineligible, Zane begins to question whether Stoneyridge is being entirely honest with its pupils.
Zane gradually comes to realise that he can only be sure of two things: all of his peers are being lied to, and until he unearths the actual purpose of their Reviews, he and his friends could be living in more danger than they know.
