Izanami’s Choice is a clever book about an alternate 19th Century where robots and computers are already established. Izanami is a ronin (a samurai without a lord to serve) who has had to make some tough choices in his life. He knows that his way of life is on the wane, even though Japan still pays lip service to its traditions (including having an Emperor) and culture.
“It bowed and gestured again: Then it straightened, speaking only after it had returned its hand carefully to its side: ‘The door, sir.’ Itaru sighed. This jinzou had been cautiously trained. An invitation would make Itaru a legal guest, protected by Tokyo law. It was a common trick in bakuto houses and other illegal establishments. The door would be left wide open in welcome, but with no official invitation, anyone who walked through was technically a trespasser. Privately owned droids could do anything to a trespasser in their master’s home.”
Come for the assassin bots; stay for the mysteries with exotic atmosphere. Heine shares a great deal of his knowledge of Japan in constructing a believable world with many cultural touches. This is all done in a non-stop action story where we strain with Itaru to find out whether a plot (by the central computer?) to take over Japan can be stopped by a samurai and his daughter.
Itaru confronts a number of moral choices that parallel ones that our Age of Impeding AI is also considering. Heine does more than sprinkle these on top of the plot. In many instances they are given some careful consideration. Our ronin has several investigations going. Each puts him in danger until it seems that he cannot succeed or even survive.
“Itaru drew his tamiken from his sleeve. It was a black grip about the size and shape of a sword hilt. The oritatamiken was a rare tool, a gift from the Tokyo Police Department for his part in taking down the Akayoroshi clan of Yurakucho. He pressed a button on its side, and steel segments unfolded from the grip, each locking itself into place to form a full-length blade….The jinzou weakness--- the one reason Itaru could fight successfully against them at all---was their predictability. He had fought hundreds of jinzou in his lifetime, and although their skills evolved in clever ways, the basics never changed.”
If you made it through that paragraph and are interested in more, then I think you will enjoy this book.
