One has a secret, one of them saw, there's blood on the papers, who'll take the fall?

Zaina never meant to get involved. The plan was always to focus on her exams, make her dad proud.

But none of this is what she'd planned for. Chanelle never made it to the exam; Nero's convinced he saw something last night and Ysla can't stop crying.

As Zaina starts to scratch the surface of secrets which desperately want to stay hidden she begins to wonder ... how far will they go to keep her from the truth?
