Dame Anne Bishop learned a long time ago that for every fixed point in time, this a fracture point, an event that is susceptible to catastrophic changes in the timeline. And when she is catapulted back in time, she discovers first hand that London, February 1969 is one such point.
The London Event, the trap set for the Doctor by the Great Intelligence, changed the course of human history, and for Anne Travers it set into place a series of events that would see the death of her father barely a year later.
Now, waking up in the body of a woman she barely knows, Anne is faced with the idea that perhaps she can change things – not enough to damage the timeline, but enough to save her father.
Meanwhile, Sir Alistair Lethbridge-Stewart finds himself in the body of his younger self, on manoeuvres with the Scots Guards in Libya. Only, as he remembers, hes about to receive a call from his old commanding officer, Colonel Spencer Pemberton. A call that will drag into the London Event, and set him on a direct course for destiny!
Future and past are set to collide.
