The Complete XK9 Bones Trilogy: The Omnibus Edition

by Jan S. Gephardt

Can a pack of uplifted police dogs find a home among the stars . . . or will their creators hound them to extinction?

The XK9s are super-smart dogs, bio-engineered and cyber-enhanced to be cutting edge law enforcement tools. But do smart and verbal equal sapient? In the star systems of the Alliance of the Peoples, that's a legal distinction with potentially deadly consequences for XK9 Rex and his Pack of canine super-sleuths.

When Rex, his Pack, and their human allies on Rana Habitat Space Station tackle a grisly mass-murder case, more than an interstellar pleasure ship blows wide open. Now the people behind the XK9 Project, and their sponsors in the system-dominating Transmondian government, are desperate. They'll do all they can to erase the evidence of their international conspiracy, before inspectors from the powerful Alliance of the Peoples can investigate.

Will Rex and his Pack run down the perps and defend their sapience claim? Or will their enemies destroy them?

Read the entire XK9 "Bones" Trilogy, now all in one volume!
