In Toshikazu Kawaguchi's 'Before We Say Goodbye', the fourth installment of the beloved 'Before the Coffee Gets Cold' series, readers are once again invited to Funiculi Funicula, a mysterious Tokyo cafe offering a unique opportunity: to travel back in time. However, strict rules apply: you can only visit while the coffee is hot, you cannot change the present, and you must return before the coffee gets cold. This poignant novel explores new heartfelt stories of individuals seeking closure, making amends, or cherishing fleeting moments with loved ones. It's a testament to the power of connection and the enduring human desire to revisit the past, not to alter fate, but to find peace and understanding.
