In the near future of Robert Charles Wilson's Last Year, the technology exists to open doorways into the past - but not our past, not exactly. Each "past" is effectively an alternate world, identical to ours but only up to the date on which we access it. And a given "past" can be reached only once. After a passageway is open, it's the only road to that particular past; once closed, it can't be reopened.
