I had some preconceived ideas about Dan Brown, but often low expectations can lead to unexpected enjoyment.
Not in this case.
From the obvious "create a solution to a puzzle and plot backwards" storyline to the unbelievably bad writing style this was a truly awful read that I only completed as it was on our Book Club's list.
I know I'm in a minority here - just look at the sales figures, and I will admit that it was a page turner and there is some fun to be had with Dan Brown fans by repeating "ah yes, but what if it's all true?" at them in a spaced voice, or building intricate conspiracy theories around the fact that the epilogue begins on page 666, but I still think it is best avoided.
