I am all over the map with what I'm reading currently. It varies with what's close at hand and any passing whim.
I finished the "Wheel of Time" saga a few months back. I'm currently alternating some Star Wars books (right now, the Black Fleet Crisis, which isn't bad but isn't great either), The Lone Wolf gamebook series, and the "Phule's Company" series. The Wheel of Time is an excellent read if very long. Robert Aspirin's "Phule's Company" is meant as light science fiction, and is a fun read.
Here's the premise... in some future, The Space Legion is the least-respected of the military branches. Each soldier takes on a new name when he/she joins, usually wanting to break with their past. The series began with Lt Scaramouche's court martial. The General in charge of the meeting was evasive as to why they COULDN't throw the book at him. Finally, he revealed the Lt's last name was "Phule"- he was the son of the CEO of Phule-Proof Munitions, their main weapons supplier and main employer of retired Space Legionnaires. They settled on an assignment so unpleasant he'd just quit. They forced him to change his name, and gave him a promotion to Captain. Captain Jester was then put in charge of the current "omega company" -the dumping-ground for those who can't even make it in the Space Legion. Rather than just quit, Captain Jester/ Willard Phule decided to put his talents (and his finances) into turning the unit around, and the trouble REALLY started after that.
For SF, I tend to prefer lighter fare- with little heavier than the Star Wars "Legends" Extended Universe. For fantasy, I'll read the lighter stuff as well as the heavier stuff. My preferences there are for settings with coherent magic systems- the Recluce series, the Dresden Files (modern fantasy), and the Wheel of Time. I've enjoyed the Harry Potter series, but I've also noted some glaring problems with the magic system (from the last 2 books- the others held together reasonably well.)
If you want, I can recommend every single thing in either setting that I WOULD recommend, but I don't think you're looking for that.
