I read a Classics Illustrated comic strip adaptation of The Time Machine sometime between 1956 and 1960 and have been fascinated by time travel ever since. I remember thinking that, if a time traveler from 1960 spent half an hour in 2060, then "meanwhile" his acquaintances in 1960 would be awaiting his return. It has taken a lifetime to think through the implications of time travel.
Fortunately, HG Wells has illustrious successors. Poul Anderson's Time Patrol series and SM Stirling's Nantucket Trilogy are very dissimilar treatments but have intriguing parallels as the authors dramatize the consequences of their premises, a police force to prevent temporal changes and an island moved back in time. It is extremely effective when the title of a volume echoes a single phrase in its text. See On The Oceans Of Eternity, Chapter Eight, p. 134.
