There are two book series I usually recommend to people: The Stormlight saga by Brandon Sanderson and the Kingkiller Chronicles by Patrick Rothfuss. Both are wonderfully written and really leave you wanting more and more with the ending of every book.

If you want something easy to read I recommend the Dresden Files. The books are good, nothing great, but the man is possible the greatest writer, in the sense of choice of words, that I've ever seen. Reading the books is almost like you're not reading it. It's hard to explain. You are never reminded you are reading instead of living out a personal fantasy in your mind, if that makes sense.
