Calling Anna and Bennett's romance long distance is an understatement. She's from 1995 Chicago, and he's a time traveller from 2012 San Francisco. They never should have met, but they did. They fell in love, even though they knew they shouldn't. And they found a way to stay together, against all the odds.

It's not perfect, of course. Bennett is forced to skip parts of his own present in order to be with Anna in hers, and he's unable to stay in the past for more than brief periods of time. But they're sure they can make it work, somehow . . . until Bennett witnesses a single event he never should have seen, and certainly never expected to.

Will the decisions he makes from that point on cement a future that both Anna and Bennett are desperate to avoid?
