This is the story of twin sisters, Hana and Kei, who have a complicated history and even more complicated present. It is also the story of their mother, Miya/ Lillie, whose disturbing and harrowing past never leaves her, hanging like a shadow over her life and the lives of her two young daughters. The story slowly uncovers Lillie's past, while at the same time diving into the sometimes confusing relationship between the two girls, and especially dealing with a traumatic experience Hana has in a cave, which Hana does not quite remember and which Kei has been doing penance for since it happened.
Hana has been living in New York City since leaving her home, her mother, her stepfather, and her twin sister in Hawaii, soon after the cave incident. She is withdrawn, introverted, and damaged by the incident of the cave and its aftermath, and has been in therapy to try to recover her sanity and equilibrium. She hasn't, so far, succeeded, and has broken off all ties with her family, hunkered down in a quiet bookkeeping job, and lives from day to day and paycheck to paycheck.
Until her sister Kei comes for an unexpected visit, claiming only that she is bringing Hana's inheritance with her. When Hana comes back to her place to greet Kei after work, she finds a terrible crime has been committed, throwing Hana into an upheaval of emotions and her life turned upside down. Hana and Kei have to work out their past lives together, their mother's secrets, and their futures.
I found the story mysterious and compelling, but slightly murky. I'm not necessarily referring to the events (although by definition the mysteries surrounding the events here are necessarily unclear until they are illuminated), but rather to the narration, as well as to the relationships here. For example, some of Hana's immense resentment and hatred towards Kei has to do with how Kei supposedly treated her on the night of the famous cave incident, but this could have been cleared up the very next day. Ditto for Hana's resentment towards her mother, (whom she leaves and does not return to, ever) for not visiting her in the hospital in the aftermath of the cave incident. Hana is traumatized, and leaves home without speaking to anyone again after that, so for such a big consequence, it seems ridiculous that things are never explained to her by her sister and mother. Hana's relationship with her mother is also murky, as it is tainted by Hana's perceptions of their mother's love for the two girls, and her perceptions of Lillie favoring one over the other. This, too, is easily explainable, but never explained to Hana, and leaves psychic scars. Arnie, her stepfather, knows the truth about so much of this, and so could have easily told her, but apparently does not. It seems that so many loose ends, resentments and mysteries surround questions that could and should have been answered long ago. The same thing goes for the mysteries surrounding their mother. Granted, Lillie has some mental issues, but the girls grow up 1. not knowing who their father is 2. not understanding that Miya and Lillie are the same person 3. knowing nothing of their mother's background, family, home town, or experiences during the war 4. being confused by their mother's "episodes," etc. All this Lillie could have spoken about, but chose not to, leaving the girls with only mysteries about their mother, and some mysterious items (a photo of a child, a wooden yo-yo, a jade necklace) that leaves them confused and hurt.
The mystery of the crime committed to Kei at the very beginning turns out to have a very bizarre and unsatisfying answer.
