It looks like you are still active so excuse me for this being a bit late but I would definitely go with the first law trilogy by Joe Abercrombie. There is the original trilogy and 3 stand alone follow ups, would fall into the more grim fantasy genre that you seem to be looking for.

Other personal favorites for fantasy series would be- The Farseer trilogy by Robin Hobb, there are a bunch of follow up trilogies to it but that is the first.

-Broken Empire trilogy by Mark Lawrence

-a 2nd nomination for Malazan but thats a big series to tackle.

-If you want something a little more sci-fi/YA you could try Red Rising by Pierce Brown.
