An incredibly original, intelligent novel - a love story set against New York City at the dawn of the mechanical age, featuring Nikola Tesla, Thomas Edison, and J. P. Morgan.

After discovering an old photograph, an elderly antiques dealer living in present-day Los Angeles is forced to revisit the history he has struggled to deny. The photograph depicts a man and a woman. The man is Peter Force, a young frontier adventurer who comes to New York City in 1901 and quickly lands a job digging the first subway tunnels beneath the metropolis. The woman is Cheri- Anne Toledo, a beautiful mathematical prodigy whose memories appear to come from another world. They meet seemingly by chance, and initially Peter dismisses her as crazy. But as they are drawn into a tangle of overlapping intrigues, Peter must reexamine Cheri-Anne's fantastic story. Could it be that she is telling the truth and that she has stumbled onto the most dangerous secret imaginable: the key to traveling through time?

Set against the mazelike streets of New York at the dawn of the mechanical age, Peter and Cheri-Anne find themselves wrestling with the nature of history, technology, and the unfolding of time itself.
