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.

There was no World War II, no Great Depression. Poverty is declining, prosperity is increasing everywhere; social instability is rare. But Cassie knows the world isn't what it seems. Her parents were part of a group who gradually discovered the awful truth: That for decades - back to the dawn of radio communications - human progress has been interfered with, made more peaceful and benign, by an extraterrestrial entity.
