Restoration

There's been an accident in the time stream... Noel, a top operative of the Time Institute, has been duplicated in his exploration of the past. His other self is a mirror image of sorts, a dark twisted variant of Noel... His name is Leon. And Leon is a determined to change history as Noel is to preserve it. In a common time and space, they can exist simultaneously - but with different agendas. Now Noel must follow his dark half to the squalid streets and royal palaces of Restoration England - and into the blazing heart of the Great Fire of London... But how can any man hope to outwit himself? (from the back cover of the Ace Books first edition)
