Hidden in CIA agent Denis Slater's safe is an ancient reliquary found in the ruins of an old English abbey. In a secret compartment, embedded in a thousand years of rust, lies the definitive proof of the Lowenstein experiment, the astounding evidence of the CIA's greatest secret.

Brilliant young physicist Ira Lowenstein claimed to have developed a method of time travel, and offers it to the government; his only proviso, that he first use it for a trip back in time to uncover a family secret. But once they've seen that it works, the CIA insists on having it immediately. The order goes out to arrest Lowenstein.

Now Ira must play a deadly game of cat-and-mouse to start his mission. A mission that will take him back to World War II New York, an arrest for treason and an audience with a dying president that will rewrite the course of world history.

Herbert Cohen's THE CUBE ROOT OF TIME is a well crafted ingenious thriller; a successful blend of science fiction, espionage and romance.

… A time travel scenario as plausible as any - and a novel so strong that science buoys the story but doesn't overwhelm. This book - and Herbert Cohen - deserve our deepest regards. Baryon Magazine 95

THE CUBE ROOT OF TIME is one of the most well written books I have read in a long time. Cohen is a fabulous writer. His dialogue and narration makes for a wonderful read. The story is wonderful with just enough science and science fiction to make you wonder if some of it isn't true. I say read this at your very earliest convenience. It makes you think. Great book Mr Cohen. Jeannie Langston SFF world.com
