The Shadow Girl
by Ray Cummings
During the night, a mysterious tower appeared in the city park, where he was not there. And the girl ran away from him, asking for help. But the price of its salvation may mean that this city will be destroyed not once, but three times. Because the tower was the bridge of time that pitted the tyrant's future metropolis against the pirate colony of the past - to turn today's city into a battlefield! One of Cummings' finest works, The Shadow Girl, remains fully readable and entertaining, even though it was first published eighty years ago.
