Spoilers
A pretty decent conclusion to the series, there were a lot of entertaining parts, great characters, and quite a few twists and turns. Unfortunately, there were also some boring and predictable parts in between all the goodness, not to mention the odd insufferable character or two.
-I didn't enjoy how long it took for things to really kick off, everything was so slow and there was way too much set up/build up to the last part of the story. Also, some of the action scenes were really dragged out and described poorly, I had to keep re-reading to make sense of what was going on.
-I liked most of the characters, they all had their own little missions going on and weren't just there to run around after the main character. Yukiko, Burruu, Michi, Kin, Akhito, Kaiah and Hana were all great. I despised Kairo, Kensai, and Hiro though, they were so pathetic and easy to hate.
-I was so pissed that Burruu, Michi and Akhito died, they were the best characters. They deserved happy endings more than anyone else, I guess they had to die though since their deaths would be sadder than anyone else's.
-I loved all the various relationships between characters, especially the friendships and bonds between Yukiko/Buruu, Hana/Kaiah, Yukiko/Hana/Michi, Kin/Shinji, and Blackbird/Michi. The romantic relationships paled in comparison to them (though they were still good).
-I didn't think I'd like Kin again after his backstabbing in the second book, but he more than redeemed himself when it turned out he didn't actually betray Yukiko or the Kage. Kin was a little irritating though when he got all upset about Yukiko not trusting him, after the stunt he pulled he shouldn't have been surprised at her thinking the worst. Only someone truly daft would have had blind faith in him.
-I loathed Kairo, she was a rubbish Kage leader, she cared more about her own pain and revenge than the greater good of her people, she was a bitter cow who could have easily caused many deaths, she was just lucky that no-one died because of her pettiness. What made her worse was her acting self-righteous, hard done by, and as if everyone else was in the wrong when it was actually her who was. She did pull through at the end and start to care for other people but it was too little, too late for me.. She was still an insufferable twit.
-Why the fuck did Hana have to lose her powers when she lost her virginity? I'm sick of all these female characters in fantasy type books whose powers are tied to their virginity - and if they ever deign to have sex they lose them. As if them having sex has ruined them or made them less worthy or less of a person. I've never read the same thing happening to a male character. Ugh, it's such sexist bullshit.
-I actually felt quite sorry for Lady Izanami. I didn't blame her for turning evil and bitter after she gave birth to Shima, died during childbirth, ended up in hell for some reason, and was then found by her husband who refused to rescue her just because she was no longer beautiful. Why wouldn't she be vengeful after all she'd done for the world only to be cast aside by her shallow husband? I was actually kind of rooting for her.
-For a YA book the world building was actually quite rich and detailed.
-I wasn't crazy about the multiple POV's, there were way too many, I would have preferred only a few.
-Liked there being a summary at the beginning of who all the main characters were and what they'd been up to. It really helped jog my memory of what happened in the last book. The glossary at the end was helpful too.
-The main issue I had with this was was the poor editing, so many parts were needlessly dragged out and messily written. I have to say I wasn't a fan of the writing in general, it was a bit too embellished and dramatic at times, and it made things unclear.
Although, I wasn't a huge fan of the first two books, I would still recommend the series as a whole (well, to YA fantasy lovers anyway) as the story and characters did end up being quite engrossing and engaging.
