Holly is finally getting comfortable. Her relationship with Rory has stepped up and her friendship with the girls feels ever more real. But when an awful truth surfaces, all that is shattered.

Now Holly finds herself not knowing where to turn or who to trust. The warning messages she has been receiving intensify and the identity of their sender is more mysterious than ever.

At a party to celebrate Georgia's achievements at Solasta, Holly finds herself at odds with the jolly atmosphere and things reach a vicious end.

Holly's been taken right to the edge and now she's doubting every choice she's made along the way – who she's trusted, and how she's acted. The stakes are sky high and there's nowhere left to turn.

With everything seemingly out on the table, everyone must account for their behaviour and the part they've played in the terrible events of this first term – some will step up and some will slink away.

But even now there's one more card to play and, broken as she is, Holly will have to forge forward in the final battle to save Georgia from the darkness that has embroiled them all.
