The logical thing would be to tell you to start in order (with The First Law trilogy), but if you don't want to embark on such a journey without knowing if you'll like it, I'd say try Best Served Cold, which, although it has some tie-ins, can be read as a standalone.

Stephen Kings Dark Tower series still haunts me.
Terry Pratchett to keep things a little lighter.
R. A Salvatore if you want that DnD feeling.
Just the authors I could see on my bookcase from here.
It’s even on sale now. :)
