For cynical twenty-three-year-old August, moving to New York City is supposed to prove her right: that things like magic and cinematic love stories don't exist, and the only smart way to go through life is alone. And there's certainly no chance of her subway commute being anything more than a daily trudge through boredom and electrical failures. But then, there's this gorgeous girl on the train. Jane. Dazzling, charming, mysterious, impossible Jane, showing up in a leather jacket to save August's day when she needed it most. August's subway crush becomes the best part of her day, but pretty soon, she discovers there's one big problem: Jane doesn't just look like an old school punk rocker. She's literally displaced in time from the 1970s, and August is going to have to use everything she tried to leave in her own past to help her.
