Well, we knew Keribdis would have to resurface eventually. After all of the father figures Alissa has encountered along the way, I was a little distressed that the only major female character turns out to be what amounts to the wicked stepmother. The other female characters that pop up throughout the books are never explored, (even Alissa's mother is hardly mentioned) and Silla is too much the fragile child to be interesting.
However, Keribdis is a strange 'bad guy' to me...clearly she earned Useless's love at some point, and occasionally they talk of her beauty as though that shows her good side. But sometimes it sounds as like she was always a controlling drama queen and so I'm not clear on why the others stood by here with only meager attempts to dissuade her. Are Masters really so easily controlled? Perhaps that also ties in the feral mind being forced into submission, though in that case I'd like to hear how Keribdis was able to gain such power with hers also supposedly suppressed.
At any rate, though I had issues with certain points, I still thought that this book wrapped things up rather nicely. While I didn't care for the other Masters on the island like I did the other characters in book 3, and so didn't care what happened to them, I did want to see how it played out for our main characters. I wanted a little better for Connen-Neute as I didn't fully understand the appeal of his relationship. Talon's story wasn't unexpected, but did throw in a nice twist at the end. I wanted Sati or Beast to somehow reappear to wrap up the ending of the love triangle, and didn't buy how Alissa did get to make a choice, but then still ended up with it basically decided for her anyway, and I don't think she would have allowed it to end as it did.
Nevertheless, I found myself mulling over all the ways identity and love collided throughout the book. Even excluding Alissa's familial relationships with Useless and Redal-Stan, more so than we see with her real parents, and her brotherly relationship with Connen-Neuete. We see so many different examples of how romantic love plays out, with Alissa and Beast and Strell and Lodesh, Sati and Lodesh (did letting go of love to prevent pain spare her anything? and why does Lodesh find anything positive in love after all his losses? how does love of his city compare to romantic love?), Useless and Keribdis (did she love at all? and how does Useless pick between love and protecting others?), Bailic and Alissa's parents (never clear on what happened between him and her mother, but is his ability to kill his only friend a breaking point or just a glimpse at how broken he already was?), Connen Neute devloping a romance (did he just lack confidence and need to find himself, or was it his raku nature to avoid relationships and his experiences with Alissa helped humanize him?) I don't know if the author was intentionally exploring love or if it just became a recurring theme, but that is one thing I was left with that gave the series more impact. So that's why I gave the final book a better review than the others...in the end I think it came together with more complexity than I had anticipated and made it one I'll have to reread with those questions in mind.
