Co-written by one of the UK's leading counter-terrorism experts, The Sleep of Reason is a tense and compelling thriller about toxic politics and the radicalisation of young men.

A brutal massacre at a theme park leaves eight dead and triggers a wave of extremist violence across Britain.

On the trail of the killer is Detective Superintendent SOPHIE GABRIEL, who must confront her past as she races to stop rival Islamist and neo-Nazi terror groups bringing a deadly campaign of violence to Britain’s streets.

As community tensions rise, the coalition government appears to be exploiting the crisis for its own ends. In the midst of a political and media whirlwind, Gabriel and her team must stop a ruthless terrorist attack that could leave hundreds dead.
