The first book in the five million-copy bestselling magical realism series

If you could go back in time, who would you want to meet?

In a small back alley of Tokyo, there is a café that has been serving carefully brewed coffee for more than one hundred years. Local legend says that this shop offers something else besides coffee—the chance to travel back in time.

Over the course of one summer, four customers visit the café in the hopes of making that journey. But time travel isn’t so simple, and there are rules that must be followed. Most important, the trip can last only as long as it takes for the coffee to get cold.

Prepare to meet four visitors, each of whom is hoping to make use of the cafe’s time-travelling offer in order to:

• confront the man who left them
• receive a letter from their husband whose memory has been taken by Alzheimer's
• see their sister one last time, and
• meet the daughter they never got the chance to know.

Heartwarming, wistful, mysterious and delightfully quirky, Toshikazu Kawaguchi’s internationally bestselling novel explores the age-old question: What would you change if you could travel back in time?
