Time's Eye

Clark, Arthur C. and Stephen Baxter. Time's Eye: A Time Odyssey.  New York: Ballantine Books, 2004. A mysterious force has carved up human history, rearranging past and present so that different eras come face to face with one another.  United Nations officer Bisesa Dutt of the year 2037 finds herself catapulted into a time when the British empire, Alexander the Great, and Genghis Khan exist side by side--and are not very happy about it.  Part science fiction, part history review, Time's Eye is a joyful romp through historical impossibilities.
