The Invisible City
Brian K. Lowe, author
One moment Charles Clee is on a battlefield in France, the next he is stranded 850,000 years in the future. On a conquered Earth, haunted by mutants and super-evolved predators, he hunts for the woman who has been stolen from him. But when he finds a working time machine, his loyalties are divided between the love he has found in the future and the duty he has left in the past.
