There are some really cool concepts here and as someone with an amateurish interest in spiders, the book appealed to me. The writing style was one I enjoyed for the most part, though (to be nitpicky) there were a few sentences or short paragraphs where he repeated words and it occurred enough times that it irritated me. I felt the first half of the book in general went at a better pace than the latter; it felt like the excitement had worn off a bit by then. Some of the technology, particularly that of the spiders, seemed hand-wavey, or at the very least I struggled to imagine how it would actually work. The book really shines with its description of spider society and how they communicate with each other and other species; it was interesting to see how their social mores and understanding of science and divinity evolved over generations. Also as someone with an interest in languages both ancient and modern, I could see a bit of myself in the classicist (and main human character) Holsten - though I would have loved more detail on the linguistic problems touched on in the book!
I picked this up not realising it was part of a trilogy - it's not openly labelled as such, and I only twigged part way through reading it that this was a counterpart to 'Oryx and Crake' (which I have since picked up but have yet to read). So I feel I have perhaps missed some context to tie everything together.
I have read other Margaret Atwood books and enjoyed them (in a manner of speaking, because they've all been rather depressing on some level or other); the last one I read was 'The Blind Assassin', several years ago now but I remember that book just 'clicking' with me; there was just the right amount of detail and plot. With 'The Year of the Flood', however, there's almost too much plot going on, while I would have liked more detail in places. Overall, something about this book didn't quite ring true for me. I felt an odd distance from the characters, though I liked the two main characters well enough. I also struggled to get a sense of physical scale - for instance, there's a spa within some grounds that I pictured being like a small park, but at some point characters travel across these grounds and they are vast. Conversely, people seem to able to walk around a city quite quickly. I don't know how much of that was a failure on the author's part versus a failure in my reading comprehension.
The writing seemed very heavy-handed in parts; the naming of some things was silly (CorpSeCorps in particular - a Big Bad but can anyone take that name seriously?); I felt there was a level of smugness or preachiness, of 'don't be too consumerist, kids; now here is another eeeevil corporation'. And I am someone who agrees that many corporations have unethical practices and that we need to take better care of the planet - but there was little subtlety here. It didn't feel like a particularly believable depiction of the future.
The sexual violence - and there's a lot of it - made for very uncomfortable reading, but that was probably the point - and depressingly, when I think about it, it probably is one of the more believable aspects of the dystopia portrayed here. If women aren't safe in a 'stable' society, what hope do we have in one that is falling apart?
One positive is that the book held my interest most of the time, and I read it quite quickly, eager to see how things would turn out - though the ending was strange and inconclusive and I hope things are tied up in 'MaddAddam' (which I plan to get hold of). Others have mentioned not liking the hymns or sermons interspersed between the main action, and to an extent I agree; they could feel dull and forced when I just wanted to see what would happen next. On the other hand, there was something quite comforting about them in a book that is otherwise full of awful depressing things. Overall I thing they were a positive addition.
