Julian May’s Galactic Milieu cycle is a huge favourite of mine. It’s got future, past, 6 million years in the past and eventually beings from 6 million years in the past going to the near future. It’s a time travel fantasy saga with elements of sci-fi too.
He didn’t believe there was a paradox. In his view, only one thing happens at one point in history, and, even if you have time travel, the event is consistent if seen by all interacting at that point in space time (ignoring the “paradoxes” of relativity). He goes to pains to depict this in TimeMaster. It’s not clear to me what would happen if you actually did try to confront your grandfather and shoot him, but in Forward’s universe you wouldn’t branch to an alternate timeline. Your attempt at interferenbce isn’t a change in the stream of time – it always was part of it.
One of my favourites which hasn’t already been mentioned, is Branch Point by Mona Clee; increasingly larger attempts are made to change the past because the future is so horrible.
Eventually they end up altering history back far enough so that the USA won’t come into being! A long time since I read it; may have to dig it out again!
Another Robert Silverberg story I enjoyed was Hawksbill Station, about a prison facility placed back before much life had evolved!
Besides the above stories I listed, L. Sprague de Camp also wrote a Gun for Aristotle (Brookhaven physicist goes back to try to change some of Aristotle’s ideas) and The Glory that Was (Periclean Greece).
Special notice to Michael Moorcock’s Behold the Man (Time Traveler goes back to find Jesus)
Two that I don’t see mentioned here and that I think reasonably well of…
Pastwatch: The Redemption of Christopher Columbus is about conceding the changes inherent in viewing the past and the ethics of making changes.
Mammoth by John Varley. I like the fact that…
there’s never any real attempt to discover what the hell caused the time machine to come into being. It’s found, a mathematician attempts to figure out what it is, operates it accidentally, and deals with the consequences.
Much enjoyed but these are in your second category of one way trips - not really “time travel” stories as there is no way of seeing what the consequences are to the “present”.
(Of course we are finding this out from the Emberverse books and the next, and final, one may actually link the two timelines together :eek: )
Mike McQuay’s **Memories **had me in tears at the end.
In the book, there is a way to transfer your mind into any ancestor you had. The main character spends a lot of time as Napoleon. But this just grazes the surface of a funny, exciting, deeply emotional tale that often gets left out of time travel discussions.
At the time of it’s release it was highly thought of. It won a Philip K. Dick Award
Seconded. I also liked Anderson’s *The Corridors of Time *and The Dancer from Atlantis.
Thirding (fourthing?)** The Anubis Gates**. I read it because it was recommended in another thread here on the boards and was not disappointed. Terrific novel.
One of my other favorite time-travel novels (although no people time-travel, just messages) is Timescape by Gregory Benford.
The Artemis Fowl books by Eoin Colfer are great fun, and #6, The Time Paradox, is no exception. You should read #1-5 first, though. 
Timescape is better known as Disaster in Time, which is how it appears in TV listings and on the video.
I’ll vote for Heinlen’s, The Door Into Summer.
I’ve always like Heinlein’s The Door Into Summer.
I’ll agree that The Door into Summer was a good one (one of my favorites, in fact), but the time travel doesn’t play nearly as prominent a role as it does in many stories. It’s mostly a Rip Van Winkle story.
My favorites, Time After Time, The Doomsday Book, and Replay have already been mentioned.
There is also Slaughterhouse-Five. Nobody has done it quite like Vonnegut.
I enjoyed John Maxim’s Time Out of Mind, it also was a murder mystery/ghost story. “Every time it snows, Jonathan Corbin sees people and scenes that haven’t existed for 100 years. Is he being haunted or has he lost his mind? Sturdevant, the psychiatrist his girlfriend Gwen brings in, has another explanation: Jonathan is in the grip of “genetic memory,” in which ancestral recollections, like physical characteristics, are genetically inherited.”
I suppose The Time Traveler’s Wife by Audrey Niffenegger has not been mentioned because some consider it chick lit, but the chronologically-challenged Henry DeTamble was a fully realized character, and the structure of the time travel is complex and intriguing.
There is also The Little Book by Selden Edwards. I liked the first half better than the second.
One of my favorite movies. Did you all know it was based on a novel? I didn’t, until recently. The novel was rereleased recently and I bought it, but haven’t gotten around to reading it yet.
I didn’t see any mention of the 1632 series by Eric Flint. Similiar to Stirling’s series, this time an interstellar art accident sends a present day West virginia coal town back into the middle of the 30 Years War, and details the resulting events from that.
I like Flint’s take on the Butterfly Effect in these novels.
I’ve tried to read that, but after about 30 pages of nothing happening but the protagonists saying over and over how much they love each other, I gave up.
The first book in this series has my all-time favorite time travel scene.
When a general in the 40 Years War meets up with the people from our time and has his first look at camouflage. He’s quite impressed. “Clever bastards,” he says
Too bad.
It is definitely a novel about a love, but I found the time travel aspect imaginative and innovative–different from any other time travel novel I’ve read.
And disgusting. The sexism practically drips off the page, like rotting lube oil. I’m hardly “Mr. Sensitive,” but even I couldn’t stomach it. And if the ‘oompa loompa’ sexual servants don’t revolt you, there are other problems with the stories. Like knowingly infecting the new world with European diseases. And vice versa. Frankly, I think Frankowski was going insane towards the end. He even managed to get fired by Jim Baen (R.I.P.), and that was reportedly hard to do.
“For King And Country” by Robert Asprin and Linda Evans has a slightly differnt take on things, and works pretty well - Your body doesn’t go, just your personality matrix. And you have to share the body whenever you land with the original personality of the occupant.
While we’re at it, despite being a complete goof of a movie, “Bill and Ted’s Excellent Adventure” actually handles time travel and paradox fairly well, albeit with a very irreverant attitude.
