A discredited Barlow Bridge theory, now forgotten. Two scientists have proved otherwise and believe it can be used to travel back in time. With the outbreak of World War II, the British government invests in its possibility. Who knows? It may just help them win.
If they can travel back in time, what could they do? How could they use it to win the war or stop it before it even started? Are there rules which have to be followed? If so, what are they? What happens if you break them?
This is not an average time travel book. There is no handsome hero. There is a bastard – but it is war. There is action, and there are consequences.
