Days at the Morisaki Bookshop, by Satoshi Yagisawa
Takako, a young woman from Tokyo, quits her office job and comes to live and work in the small second-hand bookstore of her uncle, Satoru, in a small provincial town.
In her life in Tokyo, she was indecisive, reserved, and treated like dirt by her boyfriend. After summoning the courage to confront her boyfriend and tell him the truth, Takako takes a decisive step forward, leaving behind the negativity and moving on with her life.
Her uncle’s wife suddenly reappears with her husband after years of absence. As if nothing had happened. With her aunt Momoko, she heads into the mountains for a weekend. Momoko turns out to have had an abortion years ago and then struggled with life. After the mountain outing, Momolo disappears again as shyly as she has returned. Takako breaks her vow of secrecy and informs her uncle Satoru of the secret his wife is carrying. He searches and finds his wife again, and they become closer than ever.
Secretive as a Murakami. With a fine list of quoted Japanese writers at the back of the book.
