Many good suggestions given already. Hmm, let's see... Simon Canderous series by Anton Strout, Marc del Franco's Connor Grey series, Allie Beckstrom series by Devon Monk, Kim Harrison's Rachel Morgan/Hollows series, Chuck Wendig's Miriam Black series.

Oh, and how about George C. Chesbro's Mongo series.

Laura Blackstone series by Mark del Franco

Someone mentioned it above, but I really like Mike Carey's Felix Castor series.
