Frank is dying. Polly can save him, but only if she agrees to a radical plan: to time travel to 1993 for his life-saving treatment. She can only go forward, she cannot go back. And she must leave everything she loves behind, including Frank. But when something goes wrong and Polly arrives late, Frank is nowhere to be found. Completely alone, Polly must navigate a terrifying new world to find him.
