I'd give it 4.5 if I could. This is one of those unexpected delights. I didn't know the plot or even the genre before I started listening as I'd bought it years ago and never got around to reading it. I very quickly found myself completely engrossed. There was great modern quest with intricate puzzles and classic roles made relevant. It really spoke to the data loving problem solver in me. The only downside is the overwhelming one sided love of Google shown.

A bit of a rushed ending to this one I thought.

Perhaps the dullest book I have ever persisted with. Everything is so idealised. Everyone is 1 dimensional and incredibly obvious. Plot wise, there isn't one, they just trundle along without any concerns as everything falls perfectly into place in moments. I would have given it 1 star if it weren't for the fact that something did make me listen to it until the end (though perhaps I should give it minus stars seeing as it stole hours of my life).
