Fracture

Devastated by the loss of her friend and under constant threat from an unknown spy at Cimmeria Academy, Allie Sheridan is finding it hard to cope.
In Fracture, the third book in the Night School series, she’s not the only one losing it – everything is falling apart. And when Nathaniel begins to reveal his game plan, Isabelle starts to lose control.
As the school slides into a deadly morass of paranoia and suspicion, everyone is guilty until proved innocent. Anyone can be held without proof, and convicted without a trial. No one is safe.
This time Nathaniel doesn’t need to hurt them. This time they’re hurting themselves.
