I'm one of those people who has no problem going back to an old book that I enjoyed the first time round and re-reading it. In fact I'm a bit of a perennial re-reader which all started with the Lord of the Rings trilogy, which I used to read once a year. I don't do as much re-reading anymore, mostly because there are so many new books I want to pick up and bury my head into, but when I'm between books I have no compunction about picking up an old favourite.
Which was why after finishing Blueprints of the Afterlife I couldn't help but be drawn to Neal Stephenson's Anathem. I've reviewed Stephenson before, and I enjoy his writing. He's one of the few writers who I feel can truly master a complex, intricate storyline with many different plotpoints and ideas all at once.
Anathem is a lot different from Reamde. Told in the first person, it focuses on just one character and everything going on outside his storyline, while important, is peripheral. It's heavy on the science and philosophy, though it's all reimagined into a fictional world placed "upstream", perhaps, from our own. This is about 1000 pages, and at times it's dense going the first go around especially. If you're not into having a bit of a refresher course in philosophy, mathematics and physics interspersed with your fiction this will not be the book for you. If you are? Dive in. I couldn't put it down.
Lately my reading has been taking me down a somewhat philosophical path, just by dashing philosophy into my fiction. It has me ready to pick up some serious philosophical reading next, get back to some of my roots.
