This lovely jewel of a novel, set in Japan, explores the power of memory and how it shapes our lives, and how love and friendship can transcend hardship and loss.

The Professor is a brilliant mathematician, able to describe and demonstrate the most complex formulas into something simple and poetic and beautiful, but due to a traumatic head injury his short-term memory lasts only 80 minutes. The Professor spends his days in his study, working on difficult mathematics problems; everything before that fateful night in 1975 still clear and real to him, everything else more than 80 minutes old, new and confusing.

The Housekeeper, a struggling single mother, is assigned to care for him. Gradually they make a connection – the Professor pins multiple notes to his coat to help him cope with his handicap – and the Housekeeper’s young son often joins them. The Professor shares his love of numbers with them and joins the boy in his love of baseball.  Together the three form an unconventional family.

Thoughtful, poignant and bittersweet, this spare, elegant novel will stay with you long after you’ve finished.
