by Mark Rowley and David Derbyshire


Political thriller from the former Met Police Counter-Terrorism Chief


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 appear to be exploiting the crisis for their 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.

Co-written by one of the UK's leading counter-terrorism experts, The Sleep of Reason is a tense and compelling thriller which sees young men radicalised into murder and toxic politics fuelling extremism and violence.
