(from ebookjapan):
A woman is sleeping in Rinshoin in Bunkyo-ku, Tokyo. Her name is Saito Fuku. She was the nanny of Tokugawa Iemitsu, aka Kasuga Bachi. Born the daughter of Rizo Saito, the chief vassal of Mitsuhide Akechi, she lived a comfortable life, but the Honnoji Incident and the subsequent defeat of the Akechi forces in the Battle of Yamazaki sent her wandering from place to place. This is a life story of a woman who survived the Sengoku era and became a powerful figure in the inner chambers of the Tokugawa family in its infancy.
