Dog From Hell [EPUB ebook] 
Book Four of the Star Risk Series

It should have been an easy contract for the mercenaries of Star Risk, Ltd. Escort a group of snobbish, privileged – and slightly wild – girls from their finishing school on Earth to one of the luxury worlds. But that was before the kidnapping and murders started.Cerberus Systems, the massive, terrifying security firm that thunders across the galaxy, has Star Risk squarely in its sights. And the goons from the company named for a hound of hell aren’t going to let anything, or anyone, stand in their way.
