The catastrophic consequences of time travel are now impossible to ignore. Lord Luxon has set his sights on the ultimate prize: America, while, abducted to 1763, Peter and Kate begin to understand that history has arrived at a tipping point. Transformed into an oracle, Kate is able to see the future as easily as the past. Gideon does all he can to help, but he is tormented by the knowledge that The Tar Man, his nemesis, is also his brother. As they pursue him through the dark streets of eighteenth-century London, and the time quakes begin, Peter realises that this monster may hold the fate of us all in his hands.
