I had so wanted to enjoy this book as the blurb made it sound like a really original idea - someone who deals with being alone following an extinction event by sticking to a normal routine to stave off madness. Most protagonists in post-apocalyptic fiction end up trying to save the world (see First Activation), so this was a really unique - and far more plausible - idea.
But in truth I didn't really enjoy it. For the first half of the book it was a one star read for me - I felt it was over-long and the events could have been better covered in a handful of chapters if the narrative (too verbose at times) had been more tightly controlled. There were also many details about the main character that just didn't ring true (turning taps on and off even five years after the water went off?), and for me the author has fallen over himself to explain absolutely everything, which leaves the reader no room to speculate and use their own imagination to draw themselves into the story.
It's therefore very one sided, you're being spoon fed rather than being asked to think, which I personally never like in fiction. If you can learn one thing from The Road - McCarthy's book that the author was clearly inspired by - it's that less is more, and readers don't need absolutely every detail or there's no room for their own imagination to help the story evolve.
Half way through the book something happens (not going to give anything away here) which does rescue the story to some extent, and the second half of the book moves along with far more purpose. Some of the sequences are genuinely terrifying and very well depicted by the author, who had reigned in the bombastic urge in favour of a far more taut writing style.
But whilst I was glad I stuck with it to the end (I kind of liked the last chapter and the way the story ended), I'm afraid for me the damage was done in the first half of the book.
