I'm a sucker for time travel stories. Generally, I gravitate more toward realistic fiction than toward science fiction and fantasy, and that's been true since childhood. But for just as long, I've been fascinated by stories that put any sort of quirk in the space-time continuum, whether the characters are Locked in Time, reliving Groundhog Day, or just trying to get Back to the Future.
For me, the human stories trump the flux capacitors. Time travelers are classic fish out of water, and they're also magnets for deep, dark secrets about their own families. Even better, since the traveler's point of origin or destination is usually somewhere around the book or film's release date, a time travel story is a great way to look at ourselves through unconditioned eyes; we can be amazed at our horseless carriages or proud of ourselves for living without jet packs.
Other time-based premises also give us a chance to think differently about ourselves. What would we do if we experienced the same day over and over? What if we were--ugh--trapped at age 13 forever?
And how many of you wish you could go back to the moment before I got "The Time Warp" stuck in your heads?
