QUANTUM MORTIS A Man Disrupted #1: By the Book

Chief Warrant Officer Graven Tower is a ruggedly handsome military policeman who hates aliens. Fortunately, as a member of His Grace's Military Crimes Investigation Division - Xenocriminology and Alien Relations, he gets to arrest a lot of them. Sometimes he even gets to shoot them. But while he doesn't like aliens, Chief Tower does very much like Detector Derin Hildreth of the Trans Paradis Police Department, who is unmistakably human. So when Tower has the chance to investigate the mysterious murder of an alien on the streets of Trans Paradis with her, he's not about to miss the opportunity. Especially when their mutual investigation just might give him the excuse to shoot an alien or three.
