I've had a love of reading from a very young age. Going to the public library was always an adventure. I read so voraciously that I would walk out with over a dozen books and need to return for new ones a few days later. I mostly read fiction nowadays. I really enjoyed all the non-fiction I read for my anthropology, psychology, world religion, and other social science classes I've taken over the years. I've moved too many times from one apartment to another and across state lines, so I've donated or sold the majority of my collection. I still have a few dozen physical books, but much of my novel reading is done on a Kindle. I want a room in a house someday with walls of books, a sliding ladder to reach the top shelves and multiple pieces of furniture to accommodate however I feel like lounging/sprawling and reading at any given time.
As far as novels these are some of my favorite authors: Terry Pratchett, John Grisham, Mercedes Lackey, Sue Grafton, Ray Bradbury, Patrick Rothfuss, Tad Williams, Kathy Reichs, David Weber, Joe Abercrombie, Patricia Cornwell, and Jim Butcher. Fantasy, modern fantasy, science fiction, and mystery/crime. For non-fiction, it's nearly all related to food/cooking. Cook's Illustrated, Serious Eats, Bon Appetite, etc are my jam. Some of the different current news that pops up on my phone. Wikipedia and other sources for looking things up.
Lately I am thinking of dabbling in some very much brain fluff-ish reading to help stave off some sadness and frustration I've been dealing with.
