The Jack Christie Books

The Jack Christie books are time travel adventures where the hero, Jack, travels back in time to turning points in history that changed the world.


Day of the Assassins (published in the UK, US, China and Turkey), was shortlisted for the BBC History Magazine/ Historical Association ‘Young Quills Award’. It was also long-listed for the Branford Boase Award, the Book Trust Booked Up programme and the Catalyst Book Award.


'Day of the Assassins' is based around the build up to World War 1 and the assassination in Sarajevo.

'Day of Deliverance' focuses on the Elizabethan period, the Armada and the world of Shakespeare and Marlowe.

'Day of Vengeance' takes Jack to the Fall of France in 1940 and Hitler's visit to Paris, the Battle of Britain and the Nazi Vengeance programme.

'Day of Rebellion' is about China and The Taiping Rebellion in 1860.


Johnny has spoken about books, writing and history to schools and adult groups across the UK, including the Cheltenham, Edinburgh, Hay, Starlit and Borders Festivals.
