Got this one on my kindle reader from Amazon, and chewed through it in a couple of days. I'll start with the good stuff - it's certainly an engaging read, which is an accomplishment for a book in which (deliberately) pretty much nothing happens. The author has said that he's wanting to write a book about ordinary people in their day-to-day lives, and he's managed to do this admirably.
Lots of people have praised the setting and world building in this book, and I'd have to concur with them - it's a lovely conception of a universe, and a nice change from action or effects-driven science fiction writing. The engagement in the story is almost fully character driven, which lends it a nice universality.
But (and, I'm afraid, there is a but) it is, to my mind at least, a flawed novel in a few ways.
Firstly, while I can appreciate the author wanting to avoid a conflict driven narrative (and commend him for doing so), he seems to have taken the standpoint that the best way to avoid conflict is to have absolutely nothing bad ever happen to anyone. Nobody is ever really depressed. Nobody wakes up not wanting to go on shift that morning. Every trade works out brilliantly for all involved. The ship never seems to develop even a tiny fault which needs fixing. In one scene, even the filthy job of cleaning dead algae off the ship's scrubber matrix manages to come across as something of a lark for all involved. And for me, this anodyne good karma which pervaded the book also managed to strip it of some of its soul. The protagonist is named Ishmael, after the central character in Moby Dick (Indeed, the book opens with a direct nod to Herman Melville's classic), but there the parallels with the doomed voyage of the Pequod end. By the end of the book, it's closer to a trip aboard the Love Boat.
Secondly, the writing, which is by no means bad, is also by no means good. It's readable, but not - for my money at least - as polished as I'd have liked from a commercially published novel. This might well be something to do with the fact that the book - and all the others in this series - were originally 'written' and released as podcasts, and thus originally construed as audiobooks. I can certainly imagine them as effective in that format, but there's a large gap between the way people talk, and the way we read, and my feeling is that the translation from audio file to the page hasn't been entirely successful. I kept wanting to grab a red pen and give certain paragraphs a good tightening. Which wouldn't have been good for my iPad, if nothing else....
Finally, and this probably relates a little to my first point, the characterisation - particularly of the protagonist - seems just a little... off. Sure he's empathetic, interesting, clever and resourceful. But he also comes across as something of a robot. Case in point - His mother dies on the first page of the book (sorry for the spoiler, but as that event is also covered in the blurb and marketing material for the book, I figure it's not a huge one). We're told he feels disconnected and a sense of loss, and a couple of times later in the book other characters pay lip service to this fact, but - and here's my problem - in real terms it doesn't really seem to effect him. There are none of the stages of grieving - no denial, no anger; Ish just seems to jump straight to a kind of resigned acceptance, and then promptly moves on with his life. And this, for me, didn't ring true - right from the outset. It also made me regard his relationships with all the other characters with a kind of underlying distrust.
Overall, then, this is - despite everything I've just said - still worth a read. It's a nicely conceived idea, and a clever variation on a lot of classic science fiction, in that it takes what are essentially universal human experiences and uses them to drive the story, rather than relying upon clever setting ideas or advanced technology. It's engaging and readable, and I have no doubt that at some point I'll work my way through the rest of the books in the series (though I'm going to wait a while, until they're all available on kindle - the second book has had some very lukewarm reviews, and I suspect I'm going to want at least one after that to keep my momentum up...)
Worth a look, though I'd suggest doing your homework on it first.
