Iron Druid Chronicles by Kevin Hearne. You'll love Oberon's voice. Oberon is an Irish wolfhound.
Urban fantasy, if you liked Dresden you'll like this.

White Trash Zombie series by Diana Rowland. Amazing and fun spin on zombie genre. It's not what you expect. Great narrator.

I finished both of them this year on audible. They are fun and light reads with great characters. They are not completed series, but there's enough of them to keep you busy until next books come out.
