She quickly learns that in traditional Kyoto, personal boundaries are firmly drawn and actions are not always what they appear.In the midst of her acculturation, Sarah learns of a family secret. During World War II, her grandmother was forced to give up one of her daughters for adoption. The child was adopted by the grandmother's sister-in-law, and the siblings were brought up as cousins, growing up on the same lane where both the biological and adoptive mother lived. Even into the present, the arrangement is never discussed. But as Sarah learns, its presence looms over the two houses. In this carefully articulated world, where every gesture and look has meaning, Sarah must learn the rules by which her mother, aunts, and grandmother live.Delicately balancing drama and restraint as only few writers can, Waters captures these women -- their deep passions and tumultuous histories -- in this tender and moving novel about the power, beauty, and importance of mother-daughter relationships.
