On the peaceful Japanese island of Teshima there is a library of heartbeats, a place where the heartbeats of visitors from all around the world are collected. In this small, isolated building, the heartbeats of people who are still alive or have already passed away continue to echo.

Several miles away, in the ancient city of Kamakura, two lonely souls meet: Shuichi, a 40-year-old illustrator, who returns to his hometown to fix up the house of his recently deceased mother, and eight-year-old Kenta, a child who wanders like a shadow around Shuichi's house.

Day by day, the trust between Shuichi and Kenta grows, until they discover they share a bond that will tie them together for life. Their journey will lead them to Teshima and to the library of heartbeats . . .

Enchanting, touching, and emotionally riveting, The Heartbeat Library is a story about loss and hope, pain and joy, reality and imagination, and the promise of healing and overcoming the odds thanks to the relationships we build and rediscover. Inspired by Les Archives du Coeur, an art installation in Japan that permanently houses recordings of the heartbeats of people throughout the world, Laura Imai Messina returns in this novel to the themes and atmospheres of her internationally bestselling novel The Phone Booth at the Edge of the World, combining a real-life pilgrimage site of healing with an unforgettable and heartwarming story.
