‘What are you looking for?’ asks Tokyo’s most enigmatic librarian, Sayuri Komachi. She is no ordinary librarian. Naturally, she has read every book on her shelf, but she also has the unique ability to read the souls of anyone who walks through her door. Sensing exactly what they’re looking for in life, she provides just the book recommendation they never knew they needed to help them find it. Every borrower in her library is at a different crossroads, from the restless retail assistant – can she ever get out of a dead-end job? – to the juggling new mother who dreams of becoming a magazine editor, and the meticulous accountant who yearns to own an antique store. The surprise book Komachi lends to each will have transformative consequences.
