Dead Weight - Magic, Mayhem, and the Law in Precinct #153, #1

Newly promoted Detective Jace Smithson has his hands full with solving the murders of ten men and the kidnapping of a unicorn capable of producing diamonds. On the surface, the crime appears to be a classic tale of greed and violence, but digging deeper reveals something sinister has come to Cauldron City. Securing the safety and security of those he swore to protect is only the beginning of Jace's problems.
Add in his relationship with the dragons of Cauldron City along with a few personal secrets, and he's the ideal target for the killer. Surviving to tell the tale will test his wit and skills in ways he never thought possible. But if he wants to obtain justice for the wronged, he will have to face his challenged beliefs and come to terms with the darker realities of the city he calls home.
