After weeks in hospital, Kate Crowley returns to school scarred, cursed and looking for revenge. But it won’t be easy: her targets are the untouchable Geistlords, influential students with the power to control the invisible monsters known as Geists. Worse, her cursed eye is making her hallucinate. And her only ally is her former best friend, who hates her almost as much as he hates the Geistlords. To get her revenge – and, maybe, win back her friend – she’ll have to use her curse to discover the truth about Geists…if it doesn’t drive her insane first.
