A hijacked spaceliner. A ruthless mastermind in a cloaked fortress. And a horrifying new alien threat that could devour the solar system.

Aboard the interplanetary luxury cruiser Hyperion, disaster strikes without warning. A lethal gas attack drops the passengers, and the vessel is forcefully dragged off course by an invisible pirate fleet. Unbeknownst to the attackers, undercover Triplanetary Secret Service Agent Conway Costigan, veteran Captain Bradley, and the fierce passenger Clio Marsden have survived the ambush. Locked in a cloaked, impenetrable planetoid ruled by the sinister genius "Roger", the trio must plot a desperate escape.

But Earth's massed armadas and Roger's high-tech marauders are completely unaware of an even greater cosmic terror lurking in the void. From the depths of a distant blue-sunned world, the Nevians—giant, four-legged, amphibious scientists wielding god-like technology—have arrived in search of an invaluable resource: iron. To them, human fleets and pirate fortresses are nothing but raw metal to be melted down into slag!

Why you will love this audiobook: If you crave the adrenaline-fueled origins of Science Fiction, this is where the modern Space Opera was born! Filled with galaxy-spanning battles, brilliant undercover agents, daring escapes, hard-science futuristic weapons, and cosmic alien contact, this classic adventure delivers action and imagination at the speed of light. Fans of retro sci-fi thrillers, vintage interstellar warfare, and pulp-era heroes will be utterly captivated by this milestone of galactic literature.

About the Author: Edward Elmer "Doc" Smith (1890-1965) is universally recognized as the father of the space opera. With his legendary Skylark and Lensman series, his visionary writing established the foundational tropes of cosmic science fiction.
