Last year I was wildly into historical romance, but this year was dominated by sci-fi/fantasy and non-fiction. You can see the whole list, with my comments, but I figured I'd just highlight my favorites for now.
Every volume of this book is amazing. Like, literally. Science is amazing. Anyway... This edition did have 2 articles in common with the above compilation, but it's worth reading even if only for the fantastic forward by physicist Michio Kaku.
