Steven Erikson's the Malazan Book of the Fallen series is my favorite of all time. Really intricate, great writing, and memorable characters. Also very war / military oriented which might be a turnoff for some. Another great read in a Sci-Fi / Fantasy vein is Ready Player One, which is about a scavenger hunt through a virtual reality world / MMO scape that involves real life consequences for the protagonist. If you hate 80's references you might want to pass though. Finally, more in the realm of the bizarre is Geek Love, which centers around a family of circus freaks. Really fascinating read. Hope this helps!
