Verdict: Hugely disappointing.
There's a great-novel-of-our-time to be written about privacy and online identity. This isn't it. I had great hopes for this book considering the number of rave reviews it has received but I was hugely disappointed by it. The writing, characters and plot are so clunky that I considered not finishing it - something I almost never do. Instead, I read angrily to the end, cursing a missed opportunity, and am now recovering by reading the Jim Crace.
