It took me a while to get into this book, mainly because most of my knowledge of the Elder Scrolls comes from playing Skyrim (and reading plot summaries for Morrowind and Oblivion). Still, it was nice to see an author making use of the rich setting which the Elder Scrolls provides. I'm surprised, and slightly disappointed, that only this author has written for the franchise.
Stylistically, the novel is a bit of a mess. The worst offense is how the author flips between point-of-view characters. There are roughly five main characters, in three different groups, carrying four different plot-lines. Each time, the shift between characters was jarring, ruining any immersion. On a nit-picky point, there was even a typo, which should have been fixed in the editing process, rather than appearing in the finished product.
As well, the ending felt rushed and flimsy. It was as if the author decided it would be better to end on a dramatic cliffhanger, and was too eager to get there. The book has a sequel, but honestly, I think it would have been better if it was just one continuous story. Since this book spends so much time setting up the characters and the plot, the sudden ending cheapens the story on a whole. It's hard to say that the political intrigue is interesting when it was barely focused on, and leads nowhere. Looking back on the book, it is hard to say there was much substance, when most of it was merely a sequel hook. This shouldn't be the case, the book should be able to stand on it's own merits, with the it's own, satisfying, self-contained story.
The most interesting and original parts were the scenes set within in the floating city itself. It's explored and established nicely by the two characters who arrive there, and spend time living in it. From moving through the bottom of the island (the sump, a birthing pool/dump/waterway), to the kitchens, and the places they serve, we learn about the ecosystem, and the morals (or lack thereof) which the inhabitants hold. The scenes in the big, chaotic, alchemical kitchens full of completely alien foods reminded me of the first time I watched Spirited Away -- both have a fascinating otherworldliness to them.
Probably the biggest flaw in the novel is the morality surrounding the use of souls. In the floating city, the upper classes enjoy consuming vapours and other dishes, made by diluting the souls gathered by the island's insects. The island itself is only able to float through the use of these gathered souls.
For some of our main characters, this is considered unethical and highly disturbing. Yet the one who works in the kitchen soon comes to think of it as similar to working with meat, and another character only protests against it when the souls used belongs to people he knows.
Within the universe, the capturing of souls within the aptly named soul gems, is considered common place. These are then used to power enchanted items, such as weapons or dwarven golems.
My point is, I feel like the author missed the chance to do anything interesting with this issue. It'd be refreshing to see at least one character go "hey, this is kind of fucked up." Or to realize the floating city isn't that monstrous, considering much of Tamriel does the same thing with soul gems.
But it does show compliance with the established canon, with regards to soul-powered enchantments, so I guess at least the author is showing his work somewhat.
Finally, it bothers me that of the five main characters, only one of them is female. It makes her feel like "the token chick", and it's annoying how much time is spent from the male povs.
Though this is, again, an unfortunate tendency of the Elder Scrolls. See: Azura, who is a Daedric Prince. Apparently, the Daedra are genderless beings, yet they hold male titles (Princes and/or Lords), and Azura herself is referred to by female pronouns. I mean, what. That makes no sense. I bring this up because Azura is one of the key Daedra in the book, and so it is guilty to buying into that clusterfuck.
I will read the next book, to see what happens, but I am disappointed with this book for falling so short of it's potential.
