Fantasy that are aimed at adults. I usually prefer books that have some kind of a magic system.
Some of my favorite authors are Brent Weeks, Terry Goodkind, Brandon Sanderson, George RR Martin, Joe Abercrombie, Scott Lynch, Patrick Rothfuss, Jim Butcher, Daniel Abraham, Gaiil Martin. Steven Erikson gets an honorable mention, but I find his books hard to read these days. Robert Jordan also gets an honorable mention, but his books became hit and miss after the first 3-4.
To Sum it up: A book that falls in between Dark and Epic fantasy with interesting combat/magic systems.
Another note, The Dresden Files are the first modern based fantasy series that I've ever read and enjoyed. I originally read Jim Butchers other series first, and then decided to give the Dresden Files a shot since I enjoyed the Codex of Alera.
The Simon R. Greene books are okay if you desperately need something to read, but don't expect anything uber fabulous as TDF.
The author has a great concept that draws from NeilG's Neverwhere, but the quality of writing is poor. The hints are too obvious, key events happen too soon with too little character development. And there are a few other minor things that bother me. (Like how their magic lacks rules and constraints) I'm only up to book 5 : Path's Not Taken. But if you read the first book, it is a pretty good indicator for how the rest of the series is going to be. So pick up the first one, give it a read. Your milage may vary.
If your attention span is lacking, or if you just want a quick, simple, easy to follow urban fantasy read, I would give them a shot.
