Slave Ship from Sergan 
Cap Kennedy Book 2

HUMAN VS INHUMANTo the reptilian mind — especially the intelligent type of planets like Sergan and Obrac — the lives of others were as nothing to the need for status.To the feline mind — especially to the clever advisor of the master of Sergan — the agonies of others were not only of no consequence, they could even be a source of joy.So when these two types of inhuman intelligences got together to defy the Terran orders against interplanetary kidnapping, space hijacking, and human slavery, it was definitely a case for a top-notch secret agent. Because Earth could not afford a showdown with more than one alien species at a time.The secret agent was Cap Kennedy, Free Acting Terran Envoy, and his pursuit of the SLAVE SHIP FROM SERGAN turned out to be one of his most dangerous single-handed adventures.
