Like many others here, I loved the Tales of the Otori trilogy and wanted to spend some more time with my favourite characters from it so I picked up the sequel. And like many others, I was really devastated and disappointed by this conclusion.
Others have diagnosed the problem as perhaps being that the author determined to show how the prophecy of Takeo dying at his son's hands could come true, and by insisting on being true to the prophecy, she was then less true to the characters. Especially Kaede, who deserved much better, but also Takeo himself.
I had trouble from the very beginning with Kaede, and the idea that she would be ambivalent about her extraordinary twin daughters. I know many people who despised Catelyn Stark from Game of Thrones for the way she mistreated Jon Snow - but Jon Snow wasn't even Catelyn's kid! Maya and Miki were Kaede's kids, and she gave them the Jon Snow treatment, which poisoned them and broke the family dynamic.
But then Kaede went completely off the rails. Being upset and jealous when finding out about Yuki and Hisao? Sure. Having some harsh words for Takeo, maybe even being cold to him when they met? Certainly. But them having a great love, for the ages, is supposed to mean that when she finds this out she is willing to burn down his house, kill his men, and send him to his death? No. No. Outrageous. This book transforms Kaede from an exemplar of steadfastness and loyalty, which she was in the trilogy, to a hateful, despicable figure. I will have to actively forget this book so that I can enjoy Kaede's character in the original trilogy.
Takeo is also super frustrating. His tolerance of Kaede's dislike for the twins makes him complicit in a way that makes no sense. He got to where he is through his wits - but, though he knows and anticipates Zenko's treason and Kikuta Akio's, he is unable to take any meaningful countermeasures. Why? Supposedly because he has become tired and pacifist? So tired and pacifist that he lets these people kill his men, lets Zenko and Hana kill Taku, and plunge the country back into war? Again, this makes no sense at all.
If the author had made Hisao a more formidable villain, and likewise had Lord Saga's invasion come sooner and be bigger, and taken the spotlight off the sneering and insufferable quartet of Zenko, Hana, Kono and Akio, then we could have still had a tragic fulfilment of the prophecy but without turning Takeo into a dummy and Kaede into a disloyal dupe - in other words, taking away the two things we like best about these two characters.
It is clear the author wanted the ending to be tragic, but the tragedy should have sprung from who they were - Takeo should have died somehow because he was *too* witty, too clever; and Kaede should have fallen because she was somehow *too* loyal, too steady in her love for her family and children. Instead we had to watch them be betrayed by the author into betraying their true natures, and watch their downfalls while scratching our heads thinking, "but Kaede and Takeo would never do that!"
I have to say it. If you loved the trilogy, you should probably just avoid this book altogether. Let the trilogy stand as it is.
Now I'm going to read the prequel, Heaven's Net is Wide.
