The Ivanhoe Gambit (Time Wars, 1)

FIRST ACE ORIGINAL EDITION. V/G to LIKE NEW CONDITION. Jan 1984 MASS MARKET PAPERBACK, Simon Hawke (The Wizard of 4th Street). In the 27th Century, international disputes are resolved through time travel, “clocking” soldiers from the future into conflicts of the past. It seemed like an elegant idea: wartime industries drove the economy without actually putting nations through the physical ravages of war. And since the past already happened, history could not be changed. So went the theory. What could possibly go wrong? Lucas Priest found out the hard way. Enlisting in the U.S. Army Temporal Corps seemed like an adventure compared to his boring corporate job, but after marching with the Roman legions against Hannibal, fighting Custer’s 7th Cavalry with Crazy Horse, and raiding with Attila’s savage Huns, he could have used a little boredom. And it was about to get much worse. - Amazon
