His books include The French Revolution and the People (2004), The Terror (2005) and 1789 (2008). For Head of Zeus he has written a sharp polemic, Cultural Dementia: How the West Has Lost Its History and Risks Losing Everything Else - a book that analyses the rise of the National Front in France, Trump in the USA and the right-wing nationalists at the core of the Brexit project.
