First, a sidenote: When I was in Barcelona in 2006 I went to check out the Sagrada Familia Basilica. Fun fact: it was designed by Antony Gaudi, began construction in 1882 and has an anticipated completion date of 2026.
I only bring that up because I can kind of understand Ken Follet's obsession with cathedrals. I mean, I was at Sagrada Familia for maybe an hour five years ago and I can still remember those facts. If you haven't read the book, it's set in England in the 12th century, and is basically a story about the building of a cathedral. And lets face it, building a cathedral is no ordinary task. The book is full of detail about how to build a cathedral, should you feel the urge.
The Pillars of the Earth is an entertaining read without being amazing. I was suprised to see how divided people are about it on Goodreads. It seems to be a book you either love or hate, which makes me in the minority, because I have absolutely no strong feelings about it either way. Yes the characters were pretty generic, and I was getting a bit tired by about the 800 page mark (it's an epic tale), but I still enjoyed it.
On a completely unrelated topic, I also read The Metamorphosis by Franz Kafka and I'm annoyed for two reasons: it turns out it wasn't on my list, AND I didn't like it at all. If you've read it can you please explain what the attraction to this story is because I just do not get it.
