Mostly I'm into very involved stories.
Before that I read all the Hobit/Lord of the Rings and All of the Ice And Fire/Game of Thrones books.
I was disappointed in Dune. Like greatly so. However, I totally love the Assimov books. Really enjoyed the RRRRRRRR Martin series but I had to give it up when it appeared there was no way he was going to live to get to the end of the series.
Have you ever read the Hyperion series by Simmons? I think it's incredible. It's a 4 book "series" but it's really 2 & 2. They are tied together but it's really 2 books, then 1 thread brings you to the next 2 books. Absolutely loved them. I have just picked up the first of another 2 book series he did. Not as good, but still decent.
I actually just read Fahrenheit 451 for the first time ever this winter. A little disappointing.
My goal this year is to read about 1 book/month. This is actually a lowering of the books I read. Last fall I was reading so much that I would stay up until 1am reading then be tired the next day because I wasn't sleeping enough.
I also opened Divergent last week. Just read a few pages. I often have 2-3-4-5 books going at once.
