The Complete Aliens Omnibus

Thomas Chase wakes up from cryosleep to his first day at a new job - as a pilot for a contraband drug company dropping a shipment on Fantasia, a planet hiding an elaborate drug manufacturing operation. Everything from synthetic heroin to MX7 is cooked here, in protected caves guarded by the savage Aliens. When Chase touches down on Fantasia, a chain of events begins that cannot be stopped.
After thirty years of cryosleep, Detective Anders Kramm awakens to a changed world. The Alien threat has been subdued. Company interests dominate universal trade, with powerful men willing to do anything to assure dominance over other worlds. But Kramm has a secret. He knows why the Aliens have been let loose on the surface of a contested planet.
