I read a novel about 15 years ago, with time-traveling as the main topic. People can send their current consciousness to the past or the future inside them, with 2 kind of drugs respectively. With the future there were no problems, but when they change the past in the present you can ride down the road and see a bridge with sign "Bridge exists with probability 0.5".

Can someone remember this novel?

  • Is this Dune or one of its sequels?

  • "Now Wait for Last Year"? Oct 11, 2012 at 14:32
  • @DVK,"Now Wait for Last Year" - no, all actions performed during our timeline or near-future and "close-to-reality" setting. Basically it's not fiction with imaginative Universe or far-future setting...

  • And it's not: "An Age" by Brian Aldiss, "The House on the Strand" by Daphne du Maurier or "A Quantum Murder" by Greg Mandel

There is something similar to this concept on "Flow My Tears, the Policeman Said" by k dick but i'm not sure if it is the same

  • That was my first thought as well, after reading the title and first sentence. However, none of the rest of the details seem to match.

  • @Pelirrojilla,@Beofett Sorry, not this one. In a story I'm trying to find, they are can go both ways, into the past and the future. I recall there was a young woman and a friend of protagonist, which tried to help him stop using drugs. But I don't remember finale...
