Far from Earth, the planet Nevia faces a crisis: its amphibious rulers are running out of iron, their most vital resource. Their solution is simple and ruthless. Using technology that can strip iron from anything—stone, machinery, even human blood—they set their sights on Earth.
The attack is swift and devastating. Pittsburgh is obliterated, thousands are dead, and three human captives are taken aboard the alien ship. Among them is Conway Costigan, an undercover operative for the Triplanetary Patrol.
Trapped deep within enemy territory, Costigan must turn impossible odds into humanity’s only hope. The fate of every man, woman, and child on Earth depends on one man’s courage and ingenuity.
Before Star Wars or Star Trek, there was E. E. “Doc” Smith’s epic vision of intergalactic war.
