The Invisible City

Tracking German soldiers through the muddy trenches of France, Captain Charles Clee stumbles onto something amazing--a secret archeological expedition from the far future. Discovered and trapped, he flees through their time machine and finds himself stranded nearly one million years in the future. Clee falls in love with a beautiful woman whose family has befriended him, but when she is taken from him by one of Earth's alien overlords, he finds himself the enemy of the one of most powerful men in the world. In his quest to rescue her, he is startled to learn that a working time machine may still exist somewhere. With that machine, he could return to his own time and save his men from certain annihilation, but to do so would mean abandoning his quest. Torn between love and his duty to the men who served under him a million years past, pursued by the merciless assassins of the Time Police, Clee faces war, slavery, and fantastic beasts in a race against time itself--knowing that whatever the outcome, he must lose.
