| Yeah, I was obsessed with time travel for awhile, and it had everything to do with Donnie Darko. There's a JG Ballard short story (someone travels back in time, kills a butterfly and alters the course of history forever) which I can't remember the name of right now, but it should be in any collection of his short stories, which are all very good.
Or there's always The Time Traveller's Wife?
A good theory based book is Black Holes, Worm Holes and Time Machines by JS Al-Khalili |
