One of the best series I've ever read.
By the looks of it, there is going to be a #6 and a good chance for a #7 =)
Best part, don't worry about gaps in between the books if you can't read them straight up. This one is so easy to remember. There is only a handful of characters and a simple universe where anything goes. If you manage to remember a (dead) Witch Council, 2.5 MCs (cause very prominent zombie dog for a pet) and 4 secondary characters, you are golden! Oh.... and Donald Drumpf Trump. He is a part of this book, and you just cannot forget THAT character, no matter how much you try.
yeah, now you know why I tagged this book "horror" and "humor" at the same time
PS I just want to mention: this series is urban fantasy at it's finest truest purest self. A major city, Indianapolis, to be precise, is housing all kind of magical creatures that human population is not aware of. A human detective along with his friends - a few humans with and without psy abilities and paranormal/magical creatures - battle the dark forces. It's not simply taking action in a city, it sticks to the tradition. An extra star just for that. And that makes it SIX
