Before We Forget Kindness by Toshikazu Kawaguchi

The regulars at the magical Cafe Funiculi Funicula are well acquainted with its famous legend and extraordinary, secret menu time travel offering. Many patrons have reunited with old flames, made amends with estranged family, and visited loved ones. But the journey is not without risks and there are rules to follow. Travellers must have visited the cafe previously and most importantly, must return to the present in the time it takes for their coffee to go cold. In the tradition of Toshikazu Kawaguchi's sensational 'Before the Coffee Gets Cold' series, readers will once again be introduced to a new set of visitors: The husband with something important left to say The woman who couldn't bid her dog farewell The woman who couldn't answer a proposal The daughter who drove her father away . . . In the hauntingly beautiful Before We Say Goodbye, Kawaguchi invites us to join his characters as they embark on a journey to revisit one crucial moment in time.[Bokinfo]
