The regulars at Café Funiculi Funicula are well acquainted with the whimsical ability it grants them to take a trip into the past—as well as the strict rules involved, including that each traveler must return to the present in the time it takes for their coffee to get cold. In Toshikazu Kawaguchi’s previous novels, patrons have been reunited with old flames, made amends with estranged family and visited loved ones. Now readers will once again be introduced to a new set of visitors.
