Stranded on the planet Venus, known as Amtor to its inhabitants, Earthman Carson Napier has faced countless perils to win the hand of the courageous Duare, his beloved princess, and to be bestowed with high honors and the title of prince in the powerful nation of Korva. But when a new threat strikes from out of the skies, Carson discovers his own arrival on the planet years ago may have unknowingly led the mysterious enemy to attack.

Following a trail of destruction and death, Carson, Duare, and their friends set off across wild Amtor to track down the lethal adversary. Their journey leads them headlong into battle with the Linneauns, an ancient, seemingly indestructible race dating to the dawn of the planet. But that is not Carson’s only challenge. For even as he takes on these daunting foes, an uncanny phenomenon has entangled him with two strange individuals from beyond spacetime and threatens to drive him mad. Will Carson be able to solve the mysteries of his past and the enigmatic visitors and then defeat the terrifying menace - or will the nations of Amtor be crushed beneath the Linneauns’ heel?
