The Hexologists

I received a free copy of this book as part of the Novel Suspects Insiders Club.
 Iz and Warren Wilby are magical investigators in a city full of secrets, mystery y, of course, magic. I really enjoyed the twists and turns of this story. I also appreciate that the magic system was very well developed and explained. I particularly liked the characters. I love how Iz and Warren are so different and complement each other so well. 
I will definitely continue on with this series.
