Settling Dust - The Maxwell Chronicles, #1

Detective Ava Maxwell is about to make the biggest bust of her career with the Oklahoma Arcane Police Department. She has a promising suspect on his way to custody and a sample of the dangerous drug circulating the Oklahoma City metro. All she needs now is the name and location of the sorcerer responsible for the manufacture and distribution of the drug. But when her suspect ends up dead only moments after his arrest, Maxwell's case gets turned upside down.
With only a mysterious arcane symbol and the help of a few strange allies, Maxwell must stop a killer and find the sorcerer running the biggest drug game in town. Her job, and perhaps her life, are on the line.
